PR other/87353 fix formatting and grammar in manual

The changes to invoke.texi in r242433 left some unwanted spaces that
texi2pod.pl interprets as verbatim formatting. There are also some
grammatical errors due to the removal of references to GCJ, where the
G++ driver is referred to in the plural.
