[Buildroot] [PATCH] Fix musl-based builds on ARMhf platforms.

[Vicente Bergas <vicencb@gmail.com>]

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
There are two ways of fixing this:
 1) Changing the actual location of the dynamic linker.
 2) Changing the expected location of the dynamic linker.
This patch uses option 1.
I don't know how to do option 2 and also don't know which option is better.
