MIPS: VDSO: Fix build error

Commit ebb5e78cc6 ("MIPS: Initial implementation of a VDSO") introduced a
build error.

For MIPS VDSO to be compiled it requires binutils version 2.25 or above but
the check in the Makefile had inverted logic causing it to be compiled in if
binutils is below 2.25.

This fixes the following compilation error:

CC      arch/mips/vdso/gettimeofday.o
/tmp/ccsExcUd.s: Assembler messages:
/tmp/ccsExcUd.s:62: Error: can't resolve `_start' {*UND* section} - `L0' {.text section}
/tmp/ccsExcUd.s:467: Error: can't resolve `_start' {*UND* section} - `L0' {.text section}
make[2]: *** [arch/mips/vdso/gettimeofday.o] Error 1
make[1]: *** [arch/mips/vdso] Error 2
make: *** [arch/mips] Error 2

[ralf@linux-mips: Fixed Sergei's complaint on the formatting of the
cited commit and generally reformatted the log message.]
