Greg Ungerer reports building with m68k-uclinux-gcc toolchain is broken:

Usually, we do not need to search for export symbols in the .symtab
section, but m68k-uclinux-gcc seems to be an exceptional case.
I do not know what makes it different from other toolchains.
Also, I do not know there exist other toolchains that work like that.
This series extends the symsearch feature in case we need to explicitly
search for export symbols.
Then, the last patch fixes the issue.
This series should be applicable for linux-next.
This series is too late for the current merge window, but I'd like
to fix the issue somehow by the next merge window.
Thanks for looking into this.
I can confirm this series fixes it for me (using linux-next).
