feature-arm-{neon,vfp}.inc: refactor and fix issues
* respect all 4 vfp options ('vfp', 'vfpv3d16', 'vfpv3', 'vfpv4') when setting -mfloat-abi and ARMPKGSFX_EABI, without this change it wasn't possible to use call-convention hard together with vfpv4 * move 'vfpv3d16', 'vfpv3', 'vfpv4' support from feature-arm-vfp.inc to feature-arm-neon.inc the main difference is that feature-arm-vfp.inc is included in arch-armv5.inc while feature-arm-neon.inc only in armv7*.inc, so these options should be added to TUNEVALID also only for armv7* MACHINEs. * support vfpv4 with or without neon when both vfpv4 and neon are in TUNE_FEATURES we want to set only one -mfpu parameter and to neon-vfpv4 * prevent multiple appends to ARMPKGSFX_FPU, we don't want to include e.g. -vfp as well as -vfpv4 when both "vfp" and "vfpv4" are in TUNE_FEATURES * add -mfpu=vfp for tunes with "vfp" in TUNE_FEATURES - before that we were only adding -vfp to ARMPKGSFX_FPU * add TUNE_CCARGS_MFPU variable which is used to set -mfpu parameter as well as ARMPKGSFX_FPU suffix in TUNE_PKGARCH, all enabled values are appended to it based on TUNE_FEATURES and then the last one is used in the actual param and suffix * this prevents multiple -mfpu options in TUNE_CCARGS * !!! This means we need to change TUNE_PKGARCH and PACKAGE_EXTRA_ARCHS for vfpv4, vfpv3d16, vfpv3 tunes, because the -vfp* isn't prependend multiple times. If you're using one of these new DEFAULTTUNES (which were at least partially broken anyway) and depend on working binary package feed upgrade-path, then don't forget to migrate PR service database to new TUNE_PKGARCH.
