If you don't select BR2_BINFMT_SUPPORTS_SHARED, then the only available
option amongst: static libs, static libs + shared libs, shared libs is
"static libs", which means that the "-static" flag is always passed. If
that's OK, then I'm fine with the patch.

The second sentence of your commit log is confusing however. You say
"don't mark it depend on the static library only". But it is exactly
what your patch is doing: since it's no longer select
BR2_BINFMT_SUPPORTS_SHARED, it means that after your patch is applied,
when BR2_BINFMT_FLAT_SHARED is used, the *only* possibility is static
library only.

Could you clarify?

Thanks!

Thomas
