I was able to rebuild it with the following command, which gives you a
list of ebuilds installed with KEYWORDS=~x86.

find /var/db/pkg -name \*.ebuild -print | xargs egrep "^KEYWORDS.*~x86"

There probably are scenarios where this will fail, but in my case, the
list of ebuilds that this command generated was exactly what i had in
my package.keywords.

You might like to put set noclobber in your ~/.bashrc file (assuming
your using bash), this prevents cat from doing that (you can override
it with >| )

Seems to work, many thanks, just need to massage it a bit in vim and I'm
happy again!

Just in case anyone was wondering, and for the archives, here's the full
solution, thanks to those who responded:

find /var/db/pkg/ -name \*.ebuild -print | xargs egrep "^KEYWORDS.*~x86"
| sed -e 's!/var/db/pkg/!!g' | sed -e 's/.ebuild:KEY.*//g' | sed -e
's/-[0-9][0-9]*.*/ ~x86/g' | sort -u > package.keywords-NEW

With linebreaks removed as appropriate :)

Seems to work for me anyway, the end result looks a lot like what I had
before.
