/* A very dirty trick: gcc emits references to __divdi3, __udivdi3,
__moddi3, and __umoddi3. These functions are exported and
therefore we get PLTs. Unnecessarily so. Changing gcc is a big
task which might not be worth it so we play tricks with the
assembler.
Note: in_divdi3_c is only used to avoid symbol alias on divdi3
build itself. */
