[OE-core] [PATCH v2] musl: Build outside of source tree

[Khem Raj]

musl does not use cmake/autotools etc. but plane old makefile basded
build system, which means it does not get B defined to be outside S
therefore define B explicitly to be outside S

Ensure that B is clean before configure task is run
