Some subtargets don't provide the canonical function names as
the symbol name in C libraries, and libcalls will only work if
the builtins are patched to emit the correct library name.
For example, on NetBSD, cabsl has the symbol name __c99_cabsl,
and the patching is done via netbsd_patch_builtin.
I hope that writing the detailed commit message will encourage someone
with better knowledge of GCC internals to point out a better place for
this logic. I can follow through with any suggestions :)
