That's actually how upstream does it, but then there are complications
due to the fact that some libraries only contain *.glo instead of *.o
(the former having OpenGL support enabled).
Anyway, I managed to find the problem: on arm, the linker honors
--no-whole-archive but silently ignores -no-whole-archive, so GCC's
insertion of -lgcc -lc -lgcc leads to those errors when the linker
sees the second -lgcc. (Sigh.) I have no idea why it's decided to
become so picky, or why the problem only happens on arm, though I have
to admit that the man page for ld only lists the double-dash form.
