This patch obviously isn't usable for anyone else, but UML needs a
hook or something to add libgcc and libc to the ld commands:

This fixes the flood of undefined symbols, but I still get this on the
link:
ld: warning: Cannot create .note.gnu.build-id section, --build-id ignored.
ld: warning: cannot find entry symbol _start; defaulting to 08056320
And when I run the result, I get this, which I don't understand at
all:
-bash: ./uml/linux: /usr/lib/libc.so.1: bad ELF interpreter: No
such file or directory
