ldbl-128ibm-compat: Add tests for IBM long double functions

Browse Source 
This patch creates test-ibm128* tests from the long double function tests.
In order to explicitly test IBM long double functions -mabi=ibmlongdouble is
added to CFLAGS.

Likewise, update the test headers to correct choose ULPs when redirects
are enabled.
