Subject: [PATCH 2/3] At least try building for other archs than x86*
|
||
|
|
|
||
|
|
Allow attempting to build for other architectures than x86 and x86_64,
|
||
|
|
whether or not the build will succeed or produce sane output is another
|
||
|
|
question... It emits plenty of warnings about it now though...
|
||
|
|
|
||
|
|
Configuration of the FPU controller is disabled on all but x86*, and the
|
||
|
|
uninformed hope and prayer is that defaults will be fine without messing
|
||
|
|
with them.
