I asked where all your libraries were, not just the test one. If they
are using the same paths on your host and target, don't set
solib-absolute-prefix to anything.

With solib-absolute-prefix set, GDB will search for
"/usr/arm/sysroot/lib/libc.so.6" at
"/home/dheeraj/usr/arm/sysroot/lib/libc.so.6". If that's not what you
want, you probably shouldn't set it.
Also, that warning means that the libraries GDB found on your host are
not the same versions as the ones on your target. They have to be the
same versions, or it can not step into them.
