As far as I understand it, gcc's build system takes care to consult
$(build_tooldir)/sys-include. Debian's packaging of gcc takes care to populate
it reasonably.
I have performed a fair number of builds of gcc with glibc's headers moved now
and cannot confirm the projected behavior. At present, it looks like fixing
LIMITS_H_TEST is the remaining piece to the puzzle.
