multiple miscellaneous tweaks

- set HOST_ARCHITECTURE in .profile_snowleopard
- some more configure checks
- prefer the -ggdb flag to the -g flag
- minor formatting and apostrophe-phobia
- make sure more headers define everything gettext-related properly, in
case that libintl.h does NOT do so properly
- try to fix building binutils as a framework (still broken)
