[patch, rfc] configure option for default value of solib-search-path

- Subject: [patch, rfc] configure option for default value of solib-search-path
In my cross-development environment, I need to type
set solib-search-path
/opt/hardhat/devkit/ppc/405/powerpc-hardhat-linux/lib:/opt/hardhat/devkit/ppc/405/powerpc-hardhat-linux/usr/lib:/opt/hardhat/devkit/ppc/405/target/lib:/opt/hardhat/devkit/ppc/405/target/usr/lib
when I start gdb. That's just a bit awkward; I'd prefer to have it default
to the proper value, just like the Montavista version does.
Here's a patch that lets you set the initial value of this patch at
configure time. I haven't sent in a copyright assignment, so this
won't be accepted into the gdb tree, but I'd appreciate comments on
whether this is the right approach. If it is, I'll gladly get the
copyright asignment paperwork going.
(Note: after applying the patch, you need to run autoconf.)
Thanks,
Dan
