[Buildroot] [PATCH] valgrind: disable for MIPS soft-float

[Vicente Olivert Riera]

As stated here [1], recent changes on the MIPS binutils sources have
made it necessary for GCC to pass the -msoft-float to the assembler. Due
to that, valgrind fails to build for MIPS soft-float when using a
version of binutils >= 2.25 because its using some hard-float
instructions.

However, we cannot just disable it for the soft-float and binutils >=
2.25 combination since external toolchains don't provide information
about the binutils version they use. So, instead, we simply disable it
for soft-float.
