Libunwind compilation error on ARM

[LTGZZ]

Slackware ARM -current, soft-float.

../src/.libs/libunwind-arm.so: undefined reference to AO_fetch_and_add' ../src/.libs/libunwind-arm.so: undefined reference toAO_fetch_and_add1'
collect2: error: ld returned 1 exit status
make[1]: *** [Gperf-simple] Error 1
make[1]: Leaving directory `/tmp/SBo/libunwind-1.1/tests'

Have the same error with julia's libunwind.

My Make.user :
override USE_SYSTEM_LAPACK=1
override USE_SYSTEM_BLAS=1
override USE_SYSTEM_LIBGIT2=1
override USE_SYSTEM_LLVM=1
override USE_SYSTEM_FFTW=1
override USE_SYSTEM_GMP=1
override USE_SYSTEM_MPFR=1

#14774 should probably fix this.

I don't think so. The patch I add are mainly for aarch64 and the ARM part shouldn't fix any compilation.
