Create multilib configurations based on certain *-linux-* samples.

Based on the following samples:
- x86_64-unknown-linux-gnu (-m64/-m32/-mx32)
- powerpc64-unknown-linux-gnu (-m64/-m32)
- mipsel-unknown-linux-gnu (-mabi={32,n32,64})
- sh4-unknown-linux-gnu (-m4/-m4a)
- x86_64-unknown-linux-uclibc (-m64/-m32)
- mips64el-unknown-linux-uclibc (-mabi={32,n32,64})

New samples:
- sparc64-multilib-linux-gnu (-m64/-m32)
- sh4-multilib-linux-uclibc (-m4/-m4a/-m3)
- x86_64-multilib-linux-musl (-m64/-m32)

Notably missing is arm-unknown-linux-gnu (aprofile): GLIBC does not
compile in one of the variants in its multilib set (-march=armv4t
-mthumb) due to missing atomic ops implementation.
