Since we've upgraded gnulib in the master, this bug should be fixed.

This is how RedHat seems to working around the issue:

# Currently gcc on ppc uses double-double arithmetic for long double and it
# does not conform to the IEEE floating-point standard. Thus force
# long double to be double and conformant.
%ifarch ppc ppc64
%global BUILD_FLAGS %{BUILD_FLAGS} -mlong-double-64
%endif

make check fails on test-float test on PPC.

AFAIK recent GCCs use by default the double-double arithmetic for long double on PPC and it is not compliant with the IEEE floating-point standard. Probably disabling the long double part of test-float on PPC, or adding the -mlong-double-64 to CFLAGS on PPC should resolve this.
