I'm confused by the 2 lines:
+.if defined(CROSS_BINUTILS_PREFIX)
+LD_BFD=3D${LOCALBASE}/bin/${CROSS_BINUTILS_PREFIX}-ld.bfd
Looking in /usr/local/share/toolchains/*.mk I see
CROSS_BINUTILS_PREFIX as a full path in each case
( based on devel/freebsd-gcc[69] in my context):
# grep -r CROSS_BINU /usr/local/share/toolchains/ | more
=
/usr/local/share/toolchains/aarch64-gcc6.mk:CROSS_BINUTILS_PREFIX=3D/usr/l=
ocal/aarch64-unknown-freebsd13.0/bin/
=
/usr/local/share/toolchains/amd64-gcc6.mk:CROSS_BINUTILS_PREFIX=3D/usr/loc=
al/x86_64-unknown-freebsd13.0/bin/
=
/usr/local/share/toolchains/powerpc64-gcc6.mk:CROSS_BINUTILS_PREFIX=3D/usr=
/local/powerpc64-unknown-freebsd13.0/bin/
=
/usr/local/share/toolchains/aarch64-gcc9.mk:CROSS_BINUTILS_PREFIX=3D/usr/l=
ocal/aarch64-unknown-freebsd13.0/bin/
=
/usr/local/share/toolchains/amd64-gcc9.mk:CROSS_BINUTILS_PREFIX=3D/usr/loc=
al/x86_64-unknown-freebsd13.0/bin/
=
/usr/local/share/toolchains/powerpc64-gcc9.mk:CROSS_BINUTILS_PREFIX=3D/usr=
/local/powerpc64-unknown-freebsd13.0/bin/
=
/usr/local/share/toolchains/powerpc-gcc9.mk:CROSS_BINUTILS_PREFIX=3D/usr/l=
ocal/powerpc-unknown-freebsd13.0/bin/
And when I look in /usr/srcv/Makefile.inc1 I see:
=
/usr/src/Makefile.inc1:CROSS_BINUTILS_PREFIX=3D/usr/local/${TARGET_TRIPLE}=
/bin/
Having an overall path structure like:
${LOCALBASE}/bin/usr/local/powerpc64-unknown-freebsd13.0/bin/-ld.bfd
seems strange (using powerpc64 as an example).
