# strip any static/PIE-forcing flags from a global build-flags policy
# (-static-pie, -static, -fno-pie, -no-pie) before building: libltdl
# (this port's own portable-dlopen library) builds a real shared/
# loadable object (libltdl.so) as part of its normal build, which a
# static-pie crt startup object can't link against ("undefined
# reference to `main'" out of rcrt1.o -- it's meant for a static-pie
# EXECUTABLE, not a shared library). nothing needs libtool's own
# binaries to be static-pie -- it's a build-time tool, same reasoning
# as languages/perl5's own identical strip.
