These two commands are different, but they both have their utility. It
really depends on your usage. If GDB is looking for the target library
"/usr/lib/mylib.so", it will look at (in that order):

1/ $sysroot/usr/lib/mylib.so
2/ foreach dir in $solib-search-path
       $dir/usr/lib/mylib.so
3/ foreach dir in $solib-search-path
       $dir/mylib.so
4/ some other places not related to the variables of interest here

I my experience $sysroot is simpler to use. You just have to have a copy
of your target filesystem on your development machine and point sysroot
at it. It's also more deterministic, as there's no possible mismatch
between identically named libraries.

I don't really understand how it could be less 'reliable' for you, do
you have a specific example in mind? Something that maybe should be
fixed in GDB?
