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. |
