>Description:

Since we build llvm for mesa now, using MKDEBUG=yes with build.sh requires
a lot more RAM than before. This machine used to build -current fine, but
now trashes to death.

I guess the generated LLVM debug info is also totaly useless for all
practical purposes, so maybe MKDEBUG should be disabled for that part
of the build?

>How-To-Repeat:
./build.sh -V MKDEBUG=yes

>Fix:
n/a
