* my previous thumb related commit: commit 3e760031f91fb87c3e2f62b77a117eb41164f259 Author: Martin Jansa <martin.jansa@gmail.com> Date: Wed Feb 18 15:40:35 2015 +0100 feature-arm-thumb.inc: respect ARM_INSTRUCTION_SET when adding thumb suffix unfortunately removed conditional on "thumb" in TUNE_FEATURES, when setting ARMPKGSFX_THUMB * in case we have MACHINE without "thumb" in TUNE_FEATURES and distro setting ARM_INSTRUCTION_SET to "thumb" we end with: ARM_INSTRUCTION_SET="thumb" ARM_THUMB_OPT="thumb" ARM_M_OPT="thumb" # TUNE_CCARGS correctly not adding -mthumb TUNE_CCARGS=" -march=armv7-a -mthumb-interwork -mfloat-abi=softfp -mfpu=neon" # but ARMPKGSFX_THUMB and TUNE_PKGARCH including "t2": ARMPKGSFX_THUMB="t2" TUNE_PKGARCH="armv7at2-vfp-neon" # causing following error: Error, the PACKAGE_ARCHS variable does not contain TUNE_PKGARCH (armv7at2-vfp-neon).

- Initial Revision
The ARM architecture definitions are split among a number of files. The primary definitions for the variables are handled by the core arch-arm.inc file.
TUNE_ARCH is set to either "arm" or "armeb" depending on the value of the existence of the "bigendian" feature in a given tune.
A small set of ARM specific variables have been defined to allow TUNE_PKGARCH to be automatically defined. Optimized tunings must NOT change the definiton of TUNE_PKGARCH. TUNE_PKGACH_tune- will be ignored. The format of the package arch is enforced by the TUNE_PKGARCH default. The format must be of the form: [t][e][hf][b][-vfp][-neon]
TUNE_PKGARCH is defined as: ${ARMPKGARCH}${ARMPKGSFX_THUMB}${ARMPKGSFX_DSP}${ARMPKGSFX_EABI}${ARMPKGSFX_ENDIAN}${ARMPKGSFX_FPU}
ARMPKGARCH - This is the core package arch component specified by each tuning. This is the primary identifier of a tuning. Usual values are: arm, armv4, armv5, armv6, armv7a, etc.
ARMPKGSFX_THUMB - This is the thumb specific suffix. Curently it is defined in feature-arm-thumb.inc.
ARMPKGSFX_DSP - This is the DSP specific suffix. Currently this is set to 'e' when on armv5 and the dsp feature is enabled.
ARMPKGSFX_EABI - This is the eabi specific suffix. There are currently
two defined ABIs specificed, standard EABI and Hard Float (VFP) EABI.
When the callconvention-hard is enabled, "hf" is specified, otherwise it
is blank.
ARMPKGSFX_ENDIAN - This is the endian specific suffix. It is defined in the core arch-arm.inc file.
ARMPKGSFX_FPU - This is the FPU specific suffix. The suffix indicates specific FPU optimizations. 'vfp' and 'neon' are both defined.
