Lzop isn't that common and it's only needed for a fairly specific setup, wouldn't it make more sense to build it if needed using the host infrastructure we have instead?

Yes, it makes sense. I'll rewrite the patch. What do you think about letting user to specify kernel compression:
Kernel->Compression method->gzip

                                                    ->lzma
                                                    ->lzo

Then I could combine these two issues.

That makes sense on ARM when zImage is selected, but might not for other archs. From a quick look in the kernel sources it seems to be available on:

arm, blackfin, mips, s390, sh, x86

So atleast ppc, avr32 and sparc are missing.
