Patch: move lang_specific_driver after setup of cc_libexec_prefix

Wed Jan 6 15:06:00 GMT 2010

gcj is not relocatable because the libexec prefix is set *after*
lang_specific_driver is called. Unfortunately, lang_specific_driver
needs to know the libexec prefix to pass it to ecj1. I can't see any
reason why lang_specific_driver needs to be called before the libexec
prefix is set, and it doesn't seem to break anything.
Fixed thusly, bootstrapped x86_64 GNU/Linux.
OK?
Andrew.
