 I'm trying to compile GHC for a big endian MIPS target (MIPS 24Kc, Atheros
 AR9330). The generated code for the `negateFloat` function has the
 following line:

 `%ln3uf = fsub float 0x0000000000000080, %ln3ue`

 But the constant should be `0x8000000000000000` instead.

 See todays discussion in #ghc between wereHamster and rwbarton for more
 details and possible hints how/where to fix this.
