Use rcrt1.o%s/grcrt1.o%s to relocate static PIEhjl/pie/master
crt1.o is used to create dynamic and non-PIE static executables. Static PIE needs to link with rcrt1.o, instead of crt1.o, which is also used by musl libc and OpenBSD: https://gcc.gnu.org/ml/gcc/2015-06/msg00008.html to relocate static PIE at run-time. When -pg is used with -static-pie, grcrt1.o should be used. * config/gnu-user.h (GNU_USER_TARGET_STARTFILE_SPEC): Use rcrt1.o%s/grcrt1.o%s for -static-pie.
