Illegal instruction on sparc64

[d-torrance]

On the sparc64 build of the 2.5.0rc0 package for Debian experimental, all the tests fail, e.g.,:

../build-aux/test-driver: line 112: 367433 Illegal instruction     "$@" >> "$log_file" 2>&1
FAIL: test-fdot

It looks like some instruction set isn't available. In previous versions, there were various --disable-* options to configure that could be used to disable instruction sets, but this feature appears to have been removed since the last release (I believe in #293).

This is probably due to a compilation of the library on a different architecture than the one where the package has been tested on. By default we now pass -march=native option to the compiler. You can disable this by passing the --without-archnative option to the configure script.
Please let us know if it fixes the problem.

Yes, --without-archnative did the trick on sparc64 for the 2.5.0rc1 package in Debian experimental. Thanks!
