objtool: Allow nested externs to enable BUILD_BUG()
Currently BUILD_BUG() macro is expanded to smth like the following:
do {
extern void __compiletime_assert_0(void)
__attribute__((error("BUILD_BUG failed")));
if (!(!(1)))
__compiletime_assert_0();
} while (0);
If used in a function body this obviously would produce build errors
with -Wnested-externs and -Werror.
Build objtool with -Wno-nested-externs to enable BUILD_BUG() usage.
