I use the following settings:

BR2_mipsel=y
BR2_TOOLCHAIN_BUILDROOT_MUSL=y

When trying to run non-busybox tools (such as 'nft', nftables) I get a
grumbling that libgcc_s.so.1 does not exist.

To workaround the problem, I slipped into my post-build.sh script the
following:
----
cp output/host/usr/mipsel-buildroot-linux-musl/sysroot/lib/libgcc_s.so.1
"$1/lib"
./output/host/usr/mipsel-buildroot-linux-musl/bin/strip "$1/lib/libgcc_s.so.1"
ln -f -s libgcc_s.so.1 "$1/lib/libgcc_s.so"
----

I vaguely recall there used to be a BR2_GCC_SHARED_LIBGCC that did this for
you, but it seems to have gone.  Digging around, and if I am following through
the makefiles correctly, it looks like the external toolchains do plumb this
in.  Not sure how this should actually be fixed.

Let me know if you need anything from me to help get this fixed.
