sys-libs/glibc: fix -mfpu=neon build failure, bug #657760
CFLAGS=-mfpu=neon tricked glibc into not building memcpy()
implementation. 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.
