Description of problem:

nvml fails to build from source for Fedora EPEL7 on RHELSA-7.2.


Version-Release number of selected component (if applicable):

nvml-1.0-2.el7


How reproducible:

consistently


Steps to Reproduce:
1.  On a RHELSA-7.2 host:
    mock -r epel-7-aarch64 nvml-1.0-2.el7.src.rpm
2.
3.

Actual results:

Fails to build with the following error:

cc -MD -c -o ../nondebug/libpmem/cpu.o -std=gnu99 -Wall -Werror -Wmissing-prototypes -Wpointer-arith -Wunused-macros -Wmissing-field-initializers -Wsign-conversion -Wsign-compare -Wconversion -pthread -fno-common -DSRCVERSION=\"\" -O2 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches    -DNO_LIBPTHREAD -I../include -I../common/ -fPIC ../common/cpu.c

 ^
cc1: all warnings being treated as errors
make[2]: *** [../nondebug/libpmem/cpu.o] Error 1


Expected results:

builds without errors, or excludes AArch64 as unsupported.


Additional info:

According to the spec file, this _only_ builds for x86_64:

  # Due to dependency on xmmintrin.h and some inline assembly, it can be
  # compiled only for x86_64 at the moment.

Other architectures are excluded:

  ExcludeArch:    %{ix86}
  ExcludeArch:    %{arm}
  ExcludeArch:    s390x
  ExcludeArch:    ppc ppc64 ppc64le

Would it be simpler to just make this package ExclusiveArch x86_64?  If not, please add aarch64 to the list of 'ExcludeArch', until/unless AArch64 support is added.
