[Bug 2098505] [NEW] glibc 2.41 ppc64el: math test failures

[Simon Chopin]

Public bug reported:

The glibc 2.41 test suite fails on Ubuntu:

+---------------------------------------------------------------------+
|     Encountered regressions that don't match expected failures.     |
+---------------------------------------------------------------------+
FAIL: math/test-double-acospi
FAIL: math/test-float-acospi
FAIL: math/test-float32-acospi
FAIL: math/test-float32x-acospi
FAIL: math/test-float64-acospi
touch /<<PKGBUILDDIR>>/stamp-dir/check_libc

Detailed failure pattern:

FAIL: math/test-float-acospi
original exit status 1
testing float (without inline functions)
Failure: acospi (qNaN): Exception "Invalid operation" set
Failure: acospi (-qNaN): Exception "Invalid operation" set
Failure: acospi_downward (qNaN): Exception "Invalid operation" set
Failure: acospi_downward (-qNaN): Exception "Invalid operation" set
Failure: acospi_towardzero (qNaN): Exception "Invalid operation" set
Failure: acospi_towardzero (-qNaN): Exception "Invalid operation" set
Failure: acospi_upward (qNaN): Exception "Invalid operation" set
Failure: acospi_upward (-qNaN): Exception "Invalid operation" set

Test suite completed:
  4 max error test cases,
  328 input tests,
  - with 1320 tests for exception flags,
  - with 320 tests for errno executed.
  8 errors occurred.

The bug doesn't occur in Debian.
