33 The USE flag is only effective on ppc64 and sparc where the kernel sometimes
34 is the only code that is compiled 64bit and therefore a seperate, much
35 smaller version of gcc is used to build the kernel. The flag should in fact
36 be masked everywhere except for those profiles, which is what bug 144535 [1]
37 deals with.
