So everything in Rawhide must be compiled with -fPIC?

I admit I haven't looked at rawhide redhat-rpm-config, perhaps somebody
broke something, but usually there is:
%_hardening_cflags -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1
# we don't escape symbols '~', '"', etc. so be careful when changing this
%_hardening_ldflags -specs=/usr/lib/rpm/redhat/redhat-hardened-ld
#_hardened_build 0
%_hardened_cflags %{?_hardened_build:%{_hardening_cflags}}
%_hardened_ldflags %{?_hardened_build:%{_hardening_ldflags}}
%__global_cflags -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches %{_hardened_cflags}
%__global_ldflags -Wl,-z,relro %{_hardened_ldflags}
and thus e.g. %{configure} should add the *-hardened-cc1 to
CFLAGS/CXXFLAGS/FFLAGS etc. and *-hardened-ld to LDFLAGS.
