mingw-w64 7.0.0 linker errors caused by _FORTIFY_SOURCE

[StephanTLavavej]

When building with mingw-w64 7.0.0, several components (coreutils, gdb, and sed) fail to link:

  CCLD     sed/sed.exe

collect2.exe: error: ld returned 1 exit status
make: *** [Makefile:2454: sed/sed.exe] Error 1

See https://github.com/msys2/MINGW-packages/issues/5803. The workaround is to compile with -D_FORTIFY_SOURCE=0.

Still repros with mingw-w64 9.0.0, so I don't think the upstream project(s) are properly aware of this yet.

[StephanTLavavej]

No longer repros with GCC 13.2.0 and mingw-w64 11.0.1.
