Build and install Musl-1.2.2

Reading the musl manual (it's not so much) is highly recommended before continue. Beware of sections Filesystem Layout Dependencies and Additional Files Used.

Patches

Apply a patch to fix some pathes accordingly to qLinux:

 patch -Np1 -i musl-1.2.2-path-qlnx-20220114.patch

Build It

Configure, compile and install musl the common way

$> ./configure --prefix=/qlnx \
               --includedir=/qlnx/inc \
               --syslibdir=/qlnx/lib \
               --target=$LFS_TGT

$> make

$> make install

The musl-libc doesn't come with a lot of separate helper programs like the GNU libc.
