[scc-dev] musl compilation on aarch64

Hello again.

Following up with the aarch64 support, now I'm trying to compile it
for a musl system, I'm using buildroot that uses GCC with a musl libc
compiled.

My build commands are:

make LIBPROFILE=musl config
make

Build fails while compiling something on qbe submodule:

make[4]: Entering directory

collect2: error: ld returned 1 exit status
make[4]: *** [Makefile:63: ../../bin/scc-ar] Error 1

Not sure if the commands I'm issuing are correct. Can I get some help?

By the way, there is a minor note about make:

scripts/arm64.mk:7: target 'uninstall-arm64' given more than once in
the same rule

But that is easy I think.

Thanks again.
Brian
