boost: do not allow selecting fiber module on mips32/mips64HEADmaster
The fiber module uses the cpu_relax() macro, for which the MIPS implementation uses the "pause" instruction, only available since mips32r2 and mips64r2. In order to avoid build failures on mips32/mips64, we disallow the selection of the fiber module for such architecture variants. This solution was suggested by Arnout Vandecappelle.
