gcc-454-libgcc_hidden.patch

when --disable-shared is used, libgcc is built without hidden visibility.
in combination with 2 other bugs, this leads to miscompilation of
musl libc.so on mips.
these 3 issues combined are:
1. gcc emitting useless .globl
2. gas generating OBJECT symbol rather than unknown type when it sees .globl without .type
3. libgcc.a symbols not getting hidden visibility like they should

this patch fixes 3).
