package/clang: default linker to the cross GNU
By default clang is assuming the system linker /usr/bin/ld. This
patchset updates the default to point at the cross toolchain ld.
Previously clang had been used on target only, this update is
required for host clang/clang++ to be used as a frontend for
cross-compiling.
Example build command:
output/host/bin/clang++ -mcpu=cortex-a53 \
--sysroot /<abs path>/output/staging/ \
-B /<abs path>/output/host/opt/ext-toolchain/ \
foobar.cc -o foobar
