These both sound like problems with your cross compiler, not problems
with GDB.

No, that's for target libraries. Gdb is a host program. The fact taht
build != host is irrelevant here; your "target" is i386-pc-solaris2.10,
and so is your "host". LDFLAGS is the correct place to add flags for
the host.
