patch applied (ghc-6.12/testsuite): Improve the handling of TEST_HC

[Ian Lynagh]

Fri Jan  8 13:04:00 PST 2010  Ian Lynagh <igloo at earth.li>
  * Improve the handling of TEST_HC
  We now accept TEST_HC=ghc as well as TEST_HC=/usr/bin/ghc
  The code is also a little more correct, as it will now actually
  canonicalise the value of TEST_HC if it is given on the commandline.

    M ./mk/boilerplate.mk -2 +13
