x86, asm: Fix ancient-GAS workaround
Alexander van Heukelum [Thu, 21 Oct 2010 21:30:49 +0000 (23:30 +0200)]
It turns out to generate something like this:

    printk ( ("<3>") "something");

The extra parentheses here break the UML compile.

Change the sed-program to add the parentheses only for numbers.
