[PATCH] libgloss: fix typo in porting doc

[Mike Frysinger <vapier at gentoo dot org>]

i noticed a typo in the porting doc:
-Libgloss's creation was forced initially be the cpu32 processor
+Libgloss's creation was forced initially because of the cpu32 processor

but fixing this seems like the whole paragraph needs to be reformatted due to 
long lines.  am i doing this right ?  i rarely touch texi files, so i dont 
really know the policy on them ...

 After a while it became apparent that this approach of isolating the
 hardware and systems files together made sense. Around this same time
