_FORTIFY_SOURCE=3 fail for gcc 12/glibc 2.35

Hi, _FORTIFY_SOURCE=3 fail to compile with gcc 12/glibc 2.35. Used: (GCC) 12.0.1 20220504 (prerelease) glibc ec5b79aac768 (release/2.35/master) In file included from /x86_64-unknown-linux-gnu/usr/include/features.h:490, from .../x86_64-unknown-linux-gnu/usr/include/asse

[PATCH 2/2] drop _FORTIFY_SOURCE for host build

Check for _FORTIFY_SOURCE level was made for target, not for build host. This level may not satisfy to libc on host. Fortification for build tools looks insignificant, so just drop -D_FORTIFY_SOURCE=... definition for host compiler. --- lib-host/Makefile.am | 1 + libcpu/Makefile.am | 1 + 2 fil

[PATCH 1/2] support cross compilation

[PATCH 0/2] cross-build support, updated

. Tricks in use only when cross-build detected. See also https://sourceware.org/bugzilla/show_bug.cgi?id=28891 Possible problem (not critical, IMHO): not tested for out-of-tree build. Petr Ovtchenkov (2): support cross compilation drop _FORTIFY_SOURCE for host build Makefile.am
