64-bit Generic Linux Haskell Platform doesn't warn when run on unsupported (32 bit) system

[nrnrnr]

I run a 32-bit Debian Linux system with a 64-bit kernel and some 64-bit packages (using Debian multiarch support). The only available current Haskell Platform I could find was the 64-bit Generic version. I installed it without much complaint (it wanted root permission which I refused to grant; see #212), but after installation it won't run:

: nr@homedog 18544 ; ghci
GHCi, version 7.10.2: http://www.haskell.org/ghc/  :? for help
<command line>: can't load .so/.DLL for: /usr/lib/gcc/i586-linux-gnu/4.9/../../../i386-linux-gnu/libgmp.so (/usr/lib/gcc/i586-linux-gnu/4.9/../../../i386-linux-gnu/libgmp.so: wrong ELF class: ELFCLASS32)

Running GHC fails with even more interesting error messages:

/tmp/ghc13484_0/ghc_1.s: Assembler messages:

/tmp/ghc13484_0/ghc_1.s:23:0:  Error: bad register name `%rbp)'

/tmp/ghc13484_0/ghc_1.s:24:0:  Error: bad register name `%r15'

/tmp/ghc13484_0/ghc_1.s:27:0:  Error: bad register name `%rbp)'

I didn't really expect it to run, but for the Haskell Platform audience I think a little more sanity checking would be helpful---it would be best if at install time, one of the shell scripts could detect that the host machine is missing critical libraries and doesn't support the expected target instruction set.
