Spelling fixes for translatable strings

I've run aspell on gcc.pot (just quickly skimming, so pressing
I key hundreds of times and just stopping when I catch something that
looks like a misspelling).

I plan to commit this tomorrow as obvious unless somebody finds some
issues in it, you know, I'm not a native English speaker.
Yes, I know favour is valid UK spelling, but we spell the US way I think.
I've left some *ise* -> *ize* cases (recognise, initialise), those
had too many hits, though in translatable strings just 4, so maybe
worth changing too:
msgid "recognise the specified suffix as a definition module filename"
msgid "recognise the specified suffix as implementation and module filenames"
"initialiser for a dylib."
msgid "%qE attribute argument %qE is not recognised"
