[Buildroot] [PATCH] autobuild-run: Do not build python3 with this external toolchain

[Vicente Olivert Riera]

It fails to build python3 with an error like this one:

Failed to build these modules:
_posixsubprocess

Which comes from this previous error:

/br/output/build/python3-3.4.1/Modules/_posixsubprocess.c:246:33: error:
'SYS_getdents64' undeclared (first use in this function)

The failure is caused because this toolchain uses eglibc-2.18 which
lacks the definition of the SYS_getdents64 macro for MIPS64 n64.

Fixes:
