Okay, there's reason that I've left just this part of the patch. With
the patch this way, mkelfimage builds (awesome, thanks!), but lzma fails:

make[1]: Leaving directory
`/home/amp/linuxbios/buildrom/buildrom-devel/work/unifdef/unifdef-1.0'
Building lzma...
export: 4: -fno-stack-protector: bad variable name
make: ***
[/home/amp/linuxbios/buildrom/buildrom-devel/work/lzma/lzma-443/C/7zip/Compress/LZMA_Alone/lzma]
Error 2

With quotes around $(STACKPROTECT), lzma finishes, but mkelfimage fails:

Now at patch mkelfimage-autoconf.patch
export: 5: -fno-stack-protector: bad variable name
make: ***
[/home/amp/linuxbios/buildrom/buildrom-devel/work/mkelfimage/stamps/.configured]
Error 2

Thanks a ton for this!
