It should either be the last choice, or not be done at all. An
example where it should not be done at all is when host and target are
different architectures. Looking up a symbol in an x86 library when
you're debugging a MIPS target cannot ever be correct -- but that's
what can happen today. (This is also an example of something that can
easily be checked by the solib code without worrying about the
"remote" vs. "local" distinction -- if host != target then by
definition the host libraries are wrong.)
It's certainly incorrect to look up a symbol when the host
and target architectures are different. But it's also
incorrect when the architectures are the same but the library
versions are different. For example, debugging a x86 Linux 2.4
target with an x86 Linux 2.6 host. I'd rather see a fix which
handles both situations.
Essentially, any time gdb is working with a remote target,
searching the host file system should be suppressed.
