 When trying to use a newer gcc with GHC 7.8.2, some .o files are rejected
 by the linker for containing a .text.unlikely section with the following
 message:

 {{{
 Loading package text-1.1.1.2 ... ghc.exe: panic! (the 'impossible'
 happened)

   (GHC version 7.8.2 for x86_64-unknown-mingw32):

         loadObj "C:\\Niklas\\src\\Idris-dev\\.cabal-sandbox\\x86_64
 -windows-ghc-7.8.2\\text-1.1.1.2\\HStext-1.1.1.2.o": failed



 Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug



 ghc.exe: Unknown PEi386 section name `.text.unlikely' (while processing:
 C:\Niklas\src\Idris-dev\.cabal-sandbox\x86_64-windows-
 ghc-7.8.2\text-1.1.1.2\HStext-1.1.1.2.o)
 }}}

 This comes from the ocGetNames_PEi386 function in rts/Linker.c. There is a
 list of section names recognized as code sections at line 4146- in that
 file. The fix is to add .text.unlikely there, or maybe the right solution
 is to cast the net wider and accept .text.* as code sections.
