My fix for bug 22702 introduced linknamespace test failures on s390x-linux-gnu and s390-linux-gnu because it made remainder call __feholdexcept, and the s390 __feholdexcept calls fegetenv, and remainder is in Unix98 and XPG4.2 but fegetenv isn't. This patch makes __feholdexcept call __fegetenv instead to avoid that namespace issue. Tested (compilation) with build-many-glibcs.py for s390x-linux-gnu, where it resolves the test failures. * sysdeps/s390/fpu/feholdexcpt.c (__feholdexcept): Call __fegetenv instead of fegetenv.
