[Buildroot] [git commit] valgrind: disable for MIPS soft-float

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=7baf8e45e413a411fdb3adf0175025e3e5685690
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
