Hello,
At O.S. Systems we are involved in some projects which uses musl as
libC. For those, we are doing the SDK for faster development and found
that it is currently broken on Krogoth.
Master branch has the need fixes. The fixes needed are
OE-Core:2b9ae0ab and OE-Core:fcaaabb4
commit 2b9ae0ab056e62290f2328aa0d4dd70e6f138759

musl: Create symlinks for stub libraries
Some libraries e.g. libm.so are needed to be
created so that SDKs built with distros which
disable static librararies can have the stubs
and since default linker script requires -lm
this helps in compiling applications with SDK
there are .a equivalents for these libraries
but they do not land in SDKs when static libs
are disabled distrowide

gcc-runtime, libgcc: Symlink c++ header and startup files in
target_triplet for SDK use
We build SDKs such that gcc-cross-candian is built for only one
target *-*-linux and then use -muclibc or -mmusl to let it compile
code for other libc variants. This works fine when libc = glibc
however it does not work for c++ programs when libc != glibc since
there are c++ headers installed under ${includedir}/c++/${BINV}/${TARGET_SYS}
which is fine when gcc-runtime and gcc-cross-candian uses same
--target options
gxx includedir searches in right triplet, but it fails with musl/uclibc
since gcc will look for glibc based triplet but gcc-runtime will install
them under musl/uclibc triplet.
This patch symlinks the musl/uclibc triplet to glibc triplet when
libc != glibc
This fixes SDKs for musl/uclibc

Backporting those, on top of current Krogoth branch, fixes the SDK
issues we had at the moment.
Could those be reviewed and queued for the next backport?
