The link failure when ld is linked. ld should not contain early dependencies on libc (with memcpy) as ld is responsible for loading libc. glibc has a few ways to avoid external memcpy() calls. To shrink the failure space a bit: Things that work: - CFLAGS="-pipe -march=armv7-a -O2" - CFLAGS="-pipe -march=armv7-a -O2 -mfloat-abi=hard" Things that fail: - CFLAGS="-pipe -march=armv7-a -O2 -mfpu=neon" Only -mfpu=neon seems to affect gcc code generation in a way that triggers gcc to insert memcpy() call. Next step is to check how exactly code generation changes.
For some reason string/rtld-memcpy.os is built only for non-neon case.
Posted summary and patch to https://sourceware.org/bugzilla/show_bug.cgi?id=23273#c1
The outcome of https://sourceware.org/bugzilla/show_bug.cgi?id=23273#c7 is Gentoo needs to make sure ASFLAGS contain at least the same ABI flags of CFLAGS. Upstream glibc maintainers suggest passing flags to CPPFLAGS as those are used in all ASFLAGS contexts (and in some additionalpreprocessor contests).

It's caused by the fact that -mfpu=neon was passed when building .c files, but was not passed when building .S files. This change passes CFLAGS to CPPFLAGS to apply to .S files.

Above example will use 'gcc -mno-sse4.2 -msse4' order.
