the spkg should work with the system-wide CFLAGS value. With {{{-g -O3}}}
it seems {{{HAVE_SSE2}}} is defined but SSE2 is not supported.
What is strange is that the GMP-ECM configure checks if SSE2 is really
supported,
and if it is not the SSE2 code should not be compiled.
Do you confirm that the upstream package works with {{{CFLAGS=-g -O3}}}?
