arch: BINFMT_FLAT_SHARED is not really shared for buildroot purposes
Although BINFMT_FLAT_SHARED is indeed a shared library format, it does
not support dynamic library loading with dlopen(). So for buildroot
purposes, BR2_STATIC_LIBS shouldn't be selected.
As it happens, the compiler options that are added for
BINFMT_FLAT_SHARED also make the compiler ignore the -static option, so
we can simply force BR2_STATIC_LIBS and things work out perfectly.
Therefore, remove the select of BR2_BINFMT_SUPPORTS_SHARED from
BINFMT_FLAT_SHARED, which in turn makes sure that BR2_STATIC_LIBS is
selected.
[Arnout: rewrite commit message, add explanatory comment]
