# Force gcc to use ld-wrapper.sh when calling ld.
# cflagsCompile="-B $OUT/bin/"
# The "-B$glibc/lib/" flag is a quick hack to force gcc to link
# against the crt1.o from our own glibc, rather than the one in
# /usr/lib. The real solution is of course to prevent those paths
# from being used by gcc in the first place.
# The dynamic linker is passed in `ldflagsBefore' to allow
# explicit overrides of the dynamic linker by callers to gcc/ld
# (the *last* value counts, so ours should come first).
