libstdc++: Remove handling for underscore-prefixed libm functions
[PR111638]

The checks in linkage.m4 try to support math functions prefixed with
underscores, like _acosf and _isinf. However, that doesn't work because
they're renamed to the standard names using a macro, but then 
undefines that macro again.

This simply removes everything related to those underscored functions.
