[Buildroot] [git commit] toolchain-external: fix musl-based builds on ARMhf platforms

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=066fd9017fd9a325dbf6575c9f068ab939863608
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When ARCH is arm and the hard-floating-point option is on executables
expect to find the dynamic linker at /lib/ld-musl-armhf.so.1 and not
/lib/ld-musl-arm.so.1.

This patch adjusts the logic that creates the symbolic link from the
dynamic linker path to the musl C library (since musl has everything
built into a single file).

[Thomas: tweak the commit log.]
