[Bug 841475] [NEW] Modify rules.defs to use both GCC_TARGET in addition to DEB_TARGET_GNU_TYPE if both are specified

[Tim Hentenaar]

Public bug reported:

The patch attached to this bug modifies the rules.defs file so that
-a$(GCC_TARGET) is specified in addition to -t$(DEB_TARGET_GNU_TYPE)
when calling dpkg-architecture if both are defined. This behavior is
only invoked if DEB_TARGET_GNU_TYPE is defined in the first place. This
allows one to easily build for an arch (say, "sh4") and have the
compiler be named "sh-elf" instead of "sh4-linux-gnu" without having to
modify any of the tables used by dpkg-architecture.

** Affects: gcc-4.5 (Ubuntu)
     Importance: Undecided
         Status: New
