This work was made by Victor Enriquez and then modified by Denis Carikli who was helped by Mark Hatle comments. And in the end modified by Martin Jansa to support different ARMPKGARCH and removed explicit -novfp suffix. The changes are for adding support to armv6-novfp, for building binaries for armv6 machines without vfp, for example the htc dream.

- 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-<tune> will be
ignored. The format of the package arch is enforced by the TUNE_PKGARCH
default. The format must be of the form:
<armversion>[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.
