binutils: Fix bugs found by -Wpointer-compare

Browse Source 
The MIPS bug was introduced by upstream commit 7403cb630, which failed
to account for the additional indirection introduced and also dropped
one of the checks; change it to the standard "NULL-or-empty" check as
used elsewhere in BFD, which is also what upstream now has.
