x86 tune: fix TUNE_PKGARCH definition for proper PACKAGE_ARCH
rpmbuild can not handle the PACKAGE_ARCH of these kinds:
x86_64-x32, core2-64, core2-64-x32
With these kinds of PACKAGE_ARCH the --target parameter of rpmbuild
becomes like: core2-64-x32-poky-linux-gnux32 ; And rpmbuild extracts
%_target (arch) wrongly as core2 generating these kinds of rpms with
incorrect filenames: zip-3.0-r0.core2.rpm
So this commit fixes the issue by making PACKAGE_ARCH like this:
x86_64_x32, core2_64, core2_64_x32
Now --target parameter of rpmbuild becomes like:
core2_64_x32-poky-linux-gnux32 ; And rpmbuild extracts %_target (arch)
correctly as core2_64_x32 generating these kinds of rpms with correct
filenames: zip-3.0-r0.core2_64_x32.rpm
