Mark certain hyperbolic BIST tests as Mac-only failures (bug #52627).
* mappers.cc (Facos): Relax tolerance from 2*eps to 3*eps.
* mappers.cc (Facosh): Use run-time conditional (! ismac ()) to run
regular BIST code on non-mac platforms. Create xtest which only executes on
Macs to document failure.
* asech.m: Use run-time conditional (! ismac ()) to run regular BIST code on
non-mac platforms. Create xtest which only executes on Macs to document
failure.
