package/sqlite: revert upstream change causing build issue

Upstream did a change in sqlite3.pc.in that does work with their
default build system, but not with the autoconf-based amalgamation
that we use. This issue has been reported and fixed upstream, but the
fix is not yet in any new release.

For the time being, we just revert the upstream change. We don't do a
direct revert ("git revert") as multiple upstream commits touched this
very line, so we simply revert to what it was prior to the different
changes, and to what the upstream fix ends up doing.

This issue is causing build issue for all packages that use sqlite's
pkg-config file, in a static-linking configuration.

Fixes:

+Subject: [PATCH] sqlite3.pc.in: revert upstream commits causing build issues
+
+This reverts upstream commit a2d88f6a03c9ebde3d037b0e297f47216c685381
+and a number of following commits related to the same commit. The
+sqlite build system is indeed upstream not based on autoconf, but the
+project "generates" an "autoconf-based amalgamation":
+
+  https://www3.sqlite.org/src/dir?ci=tip&name=autoconf
+
+Unfortunately commit a2d88f6a03c9ebde3d037b0e297f47216c685381 broke
+the build with the autoconf amalgamation because while @LIBS@ gets
+replaced by the autoconf machinery, @LDFLAGS_*@ do not, causing build
+failures such as:
+
+output-1/host/lib/gcc/sparc-buildroot-linux-uclibc/13.3.0/../../../../sparc-buildroot-linux-uclibc/bin/ld: cannot find @LDFLAGS_MATH@: No such file or directory
+output-1/host/lib/gcc/sparc-buildroot-linux-uclibc/13.3.0/../../../../sparc-buildroot-linux-uclibc/bin/ld: cannot find @LDFLAGS_ZLIB@: No such file or directory
+output-1/host/lib/gcc/sparc-buildroot-linux-uclibc/13.3.0/../../../../sparc-buildroot-linux-uclibc/bin/ld: cannot find @LDFLAGS_ICU@: No such file or directory
+
+This issue has been reported at
+https://sqlite.org/forum/info/e40b9b424a, and upstream says that the
+issue has been fixed in the amalgamation script by basically doing the
+same as what this commit does:
