This allows seabios-hppa to build with gcc-10. Or else the
compiler generates eg memset.isra.0 symbols instead of memset,
and the final link step fails due to missing memset.

Previous versions of gcc, for quite some time already, recognizes
this option but it does nothing since apparently no-ipa-sra is the
default. So there's no harm in adding it unconditionally, it seems.

Sending this as a proper patch with proper S-o-b, just in case.
