bfin: fix issues with internal toolchain, re-enable C++ support

The three patches allow to compile applications using TLS emulation from
libgcc or C++ applications.

The patches 892-libgcc-mkmap-symver-support-skip_underscore.patch and
893-libgcc-config-bfin-use-the-generic-linker-version-in.patch fixes how
libgcc is generated, by making the necessary libgcc symbols declared
"GLOBAL", and therefore visible outside of libgcc. This fixes a large
number of undefined reference issues (for either C++ applications or
applications using TLS emulation). This was reported as gcc PR74748.

The patch 894-libgcc-fix-DWARF-compilation-with-FDPIC-targets.patch
allows to build DWARF in FDPIC mode. This patch replaces the older
892-disable-dwarf-bfin.patch, as instead of disabling DWARF support, it
fixes it. This was reported as gcc PR68468.

In order to get C++ working without unresolved symbols, we also need to
disable symbol versioning (--disable-symvers). This is a remaining issue
in gcc which will be investigated at a later point.

Since this commit fixes C++ support in Blackfin, it re-enables the
selection of C++ support for this architecture.

+Subject: [PATCH] libgcc/mkmap-symver: support skip_underscore
+
+Some platforms, such as Blackfin, have a special prefix for assembly
+symbols as opposed to C symbols. For this reason, a function named
+"foo()" in C will in fact be visible as a symbol called "_foo" in the
+ELF binary.
+
+The current linker version script logic in libgcc doesn't take into
+account this situation properly. The Blackfin specific
+libgcc/config/bfin/libgcc-glibc.ver has an additional "_" in front of
+every symbol so that it matches the output of "nm" (which gets parsed to
+produce the final linker version script). But due to this additional
+"_", ld no longer matches with the symbols since "ld" does the matching
+with the original symbol name, not the one prefixed with "_".
+
+Due to this, none of the symbols in libgcc/config/bfin/libgcc-glibc.ver
+are actually matched with symbols in libgcc. This causes all libgcc
+symbols to be left as "LOCAL", which causes lots of "undefined
+reference" whenever some C or C++ code that calls a function of libgcc
+is compiled.
+
+To address this, this commit introduces a "skip_underscore" variable to
+the mkmap-symver script. It tells mkmap-symver to ignore the leading
+underscore from the "nm" output.
+
+Note that this new argument is different from the existing
+"leading_underscore" argument, which *adds* an additional underscore to
+the generated linker version script.
+
+Having this functionality paves the way to using the generic linker
+version information for Blackfin, instead of using a custom one.

+Subject: [PATCH] libgcc/config/bfin: use the generic linker version
+ information
+
+This commit makes the Blackfin platform use the generic linker version
+information, rather than a completely duplicated file, specific for the
+Blackfin architecture.
+
+This is made possible using the newly introduced skip_underscore
+variable of the mkmap-symver script.
+
+This also allows to get a correct linker version file, with symbol names
+matching the ones found in libgcc. Thanks to this, the necessary symbols
+are marked "GLOBAL" instead of "LOCAL", which makes them visible at link
+time, and solves a large number of "undefined reference"
+issues. Indeed, the Blackfin specific linker version script had an extra
+underscore in front of all symbols, which meant none of them matched the
+symbols in libgcc, and therefore all libgcc symbols were marked as
+"LOCAL", making them invisible for linking.

+Subject: [PATCH] libgcc: fix DWARF compilation with FDPIC targets
+
+The build of unwind-dw2-fde-dip.c currently fails for FDPIC targets with
+the following error:
+
+libgcc/unwind-dw2-fde-dip.c:167:31: error: storage size of 'load_base' isn't known
+   struct elf32_fdpic_loadaddr load_base;
+
+This patch addresses that by defining load_base with the appropriate
+type on FDPIC targets. It has been tested on FRV and Blackfin.
+
+Fixes PR gcc/68468.
