arch: allow adding a suffix to the arch-part of a tuple

Browse Source 
For some architectures, it is legit to have an alternate value in the
'architecture' part of the tuple. For example:
    armv5te-*
    armv7a8-*

Besides, some packages expect the tuple to reflect the arch variant
(eg. openMPI) to detect the variant's capabilities (eg. atomic
primitives).

This patch adds an option for the user to specify a suffix to be added
to the arch-part of the tuple.

Some architectures have multiple variants and being able to specify
the variant instead of the arch is quite convenient. This is commonly
seen for instance when "armv5tel-" is used as a prefix instead of the
more generic "arm-", or with "alphaev6-" instead of "alpha-".
Whatever you enter here will be appended to the architecture-part of the
tuple, just before the first '-'. It will override any architecture-
specific suffix that crosstool-NG may compute.
If you are not sure about what this is, leave it blank.
