Solaris/SPARC and AIX are both big endian, while avr and pru are little
endian.  As I said, without full access to the logs its hard to tell if
the failure is always the same.

There are gcc (Solaris 11.4/SPARC) and gcc211 (Solaris 11.3/SPARC, so
you'd need to configure with --enable-obsolete), as well as gcc111 (AIX
7.1.1) and gcc119 (AIX 7.2.2).  However, I've run my Solaris builds on
local machines.

It certainly smells like that.
