PURE GUESSWORK
I guess I'd try either editing linux-eabi.h like so:
#define CC1_SPEC. \
LINUX_OR_ANDROID_CC (GNU_USER_TARGET_CC1_SPEC "
%{fno-pic|fno-PIC|fpic|fPIC:;:-fPIC}", \
GNU_USER_TARGET_CC1_SPEC "
%{fno-pic|fno-PIC|fpic|fPIC:;:-fPIC} " ANDROID_CC1_SPEC)
OR perhaps modifying the definition of GNU_USER_TARGET_CC1_SPEC, which is in
gcc/config/gnu-user.h
#define GNU_USER_TARGET_CC1_SPEC "%{profile:-p}"
to
#define GNU_USER_TARGET_CC1_SPEC "%{profile:-p}
%{fno-pic|fno-PIC|fpic|fPIC:;:-fPIC}"
Either way, the HLFS book says that glibc will check for default PIC compiler,
so look for
"checking whether -fPIC is default... yes"
in the Temporary glibc's configure run to see if it works.
