Variables like CC can have spaces for additional arguments. This is particularly useful for reliably setting the sysroot.

Can we perhaps use this opportunity to make "xmakeopts" more clear via a better name, as well as uppercase it
to indicate that it is an exported variable? E.g., something like "CROSS_MAKEOPTS" is more clear to the
reader than "xmakeopts", IMHO.

I realize such a change may be a tad invasive to the eclass and possibly touch some ebuilds, so that may need
to be a separate patch that this proposed change would then be based off of.

An upper-case name suggests that the variable is exported. This variable
is also not just used for cross-compiling any more.

I hadn't noticed some older linux-headers ebuilds use this variable, so thanks for bringing that to my attention. Arguably they shouldn't, as it appears to
be an internal variable, even if it is exported, but it's been dropped in
later versions anyway. I've now made further changes. Please see the two additional patches.
