[Buildroot] [git commit master] Remove BR2_GNU_TARGET_SUFFIX and compute GNU_TARGET_NAME

commit: http://git.buildroot.net/buildroot/commit/?id=65e80a0b0bf275e0ffdbb611706bec4b1b4719b1
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Instead of asking the user about the GNU target suffix, just compute
it automatically from the other configuration options.
