Apparently, there is some error in parsing "set sysroot":

(gdb) set sysroot /tmp
No symbol "sysroot" in current context.

"set solib-absolute-prefix" does set the prefix.

IMO, if this prefix is not set by the user, the environment
symbol or path should be searched, with the host system searched
as a final choice. I can create a patch to do this if desired.
