 I have been buildng a x86_64/linux to armhf/linux cross-compiler using:

 {{{
 ./configure --target=arm-linux-gnueabihf -with-gcc=arm-linux-gnueabihf-
 gcc-5
 make -j3
 }}}

 for some time.

 However, after commit 7af29da05d, that results in:

 {{{
 "inplace/bin/ghc-cabal" check libraries/base
 "inplace/bin/ghc-cabal" configure libraries/base dist-install ""
   --with-ghc="/md-new/home/erikd/Git/ghc-upstream/inplace/bin/ghc-stage1"

   --configure-option=--with-cc="arm-linux-gnueabihf-gcc-5"
   --with-ar="/usr/bin/arm-linux-gnueabihf-ar"

 It seems that the required GCC version doesn't get passed to configuration
 for Base.
