The default behaviour of AC_RUN_IFELSE is to stop with an error if cross
compiling. Avoid this by providing the optional 4th argument to set
gcc_supports_pie=no if support for PIE cannot be detected.

This patch was sent privately to Ian but now that I've figured out the
mailing list address it probably belongs here.
One outstanding problem is for cross compilers who do want -fPIE. One
possibility would be make gcc_supports_pie ac_cv_gcc_supports_pie which
would make it over-ridable. I don't think its worth the effort just yet.
