boost: do not allow selecting fiber module on mips32/mips64
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.
