 The cross-compiling toolchain I used can be had from
 https://developer.blackberry.com/develop/platform_choice/ndk.html

 {{{
 ./configure --target=arm-unknown-nto-qnx8.0.0eabi --enable-unregistered
 }}}

 I will attach my build.mk to this ticket, but I did *not* set it to use
 LLVM for this attempt.

 I have also attached two make.log files.  One that succeeds up to #7490,
 and another quite short one that fails very fast with:

 {{{
 when making flags consistent: Warning:
     Compiler unregisterised, so compiling via C
 /tmp/ghc25531_0/ghc25531_0.hc: In function 'c2pA_entry':

 by default]

 /tmp/ghc25531_0/ghc25531_0.hc:3691:17:

 }}}

 Can current `integer-simple` not be compiled via-C for unregistered?
