Merge lp:~ams-codesourcery/gcc-linaro/generic-tuning into lp:gcc-linaro/4.6

[Andrew Stubbs]

Support for -mcpu=generic-armv7-a option.

The tuning is not complete yet, but we might as well have everything upstream has.

(Backport from FSF.)

This is OK - as a follow-up patch - you ought to also consider adding this to the BE8_LINK_SPEC similar to the way in which mcpu=cortex-a8 / march=armv7-a is added just in the case someone uses this in Big Endian mode.
