Comment(by thorkilnaur):

 I get the same error with my:
 {{{
 $ uname -a
 Linux tn24 3.2.0-39-generic #62-Ubuntu SMP Wed Feb 27 22:05:17 UTC 2013
 i686 i686 i386 GNU/Linux
 $ ghc --version
 The Glorious Glasgow Haskell Compilation System, version 7.4.2
 $ gcc --version

 }}}
 I have tried running the failing assmbly by hand with -E:
 {{{
 $ '/usr/bin/gcc' '-fno-stack-protector' '-DTABLES_NEXT_TO_CODE'
 '-Ilibraries/base/dist-install/build' '-Ilibraries/base/dist-
 install/build' '-Ilibraries/base/dist-install/build/autogen'
 '-Ilibraries/base/include' '-x' 'assembler-with-cpp' -E '-c'
 '/home/tn/tn/GHCGitRepository/ghc/delete/ghc1351_0/ghc1351_3.s'
 }}}
 The resulting output contains:
 {{{
  call 1 .get_pc_thunk.bx
 }}}
 This is in agreement with
 http://sourceware.org/bugzilla/show_bug.cgi?id=411 that describes problems
 caused by the name {{{__i686}}} unexpectedly being defined as a macro by
 {{{gcc}}}.

 As a temporary fix, adding
 {{{
 SRC_HC_OPTS     += -opta-U__i686
 }}}
 to {{{mk/build.mk}}} enables the build to proceed.

 Best regards
 Thorkil
