I've finally understood what was going on: Solaris 2 is one of the few
STDC_0_IN_SYSTEM_HEADERS targets, thus the definition of __STDC__ in the
-g3 -save-temps output changes on where in the file one is (and no
definition is actually emitted, which caused massive confusion for me).
The actual fix is simple: just test for defined(__STDC__) in libelf gelf.h
and libelf.h, as the following fix does:

This allowed me too bootstrap on Solaris 11/SPARC and Solaris 10/x86.
