This port uses symbol aliases to provide certain legacy symbols.
Following commit 1c18eaf, symbol maps were reenabled, exposing that
these legacy symbols were never actually generated.
The project tries to generate legacy symbol aliases using
__attribute__((alias)), which seems to have no effect.
Sidestep this problem for now by disabling all legacy symbols.
