package/binutils: fix build with gcc 15

Backport the upstream patch that fixes the following build error when
compiling for mips with gcc 15:

In file included from mips-opc.c:29:
mips-opc.c: In function 'decode_mips_operand':
mips-formats.h:86:7: error: expected identifier or '(' before
'static_assert'
   86 |       static_assert[(1 << (SIZE)) == ARRAY_SIZE (MAP)]; \
         |       ^~~~~~~~~~~~~

The patch is already part of upstream binutils 2.44, so we only need
it for 2.42 and 2.43.1.

All 3 versions we have of host-binutils were build-tested using the
defconfig from the autobuilder failure (see the link below) and gcc 15
on the host.

Fixes:

+Subject: [PATCH] opcodes: fix -std=gnu23 compatibility wrt static_assert
+
+static_assert is declared in C23 so we can't reuse that identifier:
+* Define our own static_assert conditionally;
+
+* Rename "static assert" hacks to _N as we do already in some places
+  to avoid a conflict.
+
+ChangeLog:
+	PR ld/32372
+
+        * i386-gen.c (static_assert): Define conditionally.
+        * mips-formats.h (MAPPED_INT): Rename identifier.
+        (MAPPED_REG): Rename identifier.
+        (OPTIONAL_MAPPED_REG): Rename identifier.
+        * s390-opc.c (static_assert): Define conditionally.
