[macppc/arm?] Unbreak devel/liboil

liboil cannot be built in the current macppc bulk:

> conv.c:78:51: error: invalid operand for instruction
> DEFINE_CLIPCONVERT_POWERPC(s8,f32, -128.0, 127.0, LFSUX, LBZ_STBUX)
(and more)

Disabling the integrated assembler fixes the build [0]. Because arm
has a similar issue, jca@ proposed to give it a chance with that flag
as well.

While here, i've moved HOMEPAGE to https.

Comments/feedback are welcome,

Charlène.
