[Launchpad Bug Tracker <2115734@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package glibc - 2.41-9ubuntu1

---------------
glibc (2.41-9ubuntu1) questing; urgency=medium

  * Merge from Debian unstable (LP: #2111998)
    Dropped changes, superseded:
    - Ignore test results on ppc64el, known issues.
    Amended:
    - d/tests: disable apparmor userns restrictions (LP #2059278)
      Changed to allow for running on non-restrictive kernels, as
      Ubuntu Apparmor sometimes lags behind the kernel.
  * Update from upstream stable branch
  * build: use envvars for CFLAGS rather than configparms (LP: #2115734)

Title:
  glibc: tests FTBFS on ppc64el with new float128 ABI

Status in glibc package in Ubuntu:
  Fix Released

Bug description:
  Currently, in the archive, testsuite failures are being ignored.
  However, once that is fixed, on ppc64el, the build fails with the
  following error:

  This test file is generated. I have confirmed that the generated file
  is identical regardless of the default ABI used by GCC.

  For comparison, a manual build of the same source tree with "mkcd
  build; ../configure --prefix; make; make check" yields the following
  gcc invocation:

  gcc /home/ubuntu/glibc-2.41/build/math/test-tgmath3-atan2.c -c
  -std=gnu11 -fgnu89-inline  -g -O2 -mabi=ibmlongdouble -Wall -Wwrite-
  strings -Wundef -Wimplicit-fallthrough -Werror -fmerge-all-constants
  -frounding-math -fno-stack-protector -fno-common -U_FORTIFY_SOURCE
  -Wstrict-prototypes -Wold-style-definition -fmath-errno  -Wno-psabi
  -mno-gnu-attribute  -fPIE       -fno-builtin <LOTS_OF_-I_FLAGS>
  -D_LIBC_REENTRANT -include /home/ubuntu/glibc-2.41/build/libc-
  modules.h -DMODULE_NAME=testsuite -include ../include/libc-symbols.h
  -DPIC -DTOP_NAMESPACE=glibc -I../soft-fp -o
  /home/ubuntu/glibc-2.41/build/math/test-tgmath3-atan2.o -MD -MP -MF
  /home/ubuntu/glibc-2.41/build/math/test-tgmath3-atan2.o.dt -MT
  /home/ubuntu/glibc-2.41/build/math/test-tgmath3-atan2.o

  One will note that the default build script adds -mabi=ibmlongdouble

  It turns out that the way we pass CFLAGS will cause the build system
  to sometimes ignore file-specific flags rather than combining them.
