Subject: [PATCH v2 nolibc 53/53] selftests/nolibc: make sure gcc always use little endian on MIPS

From: Willy Tarreau <w@....eu>

The test on MIPS stopped working after I upgraded some of my toolchains
to use the ones from kernel.org because the mips toolchain defaults to
big endian, even though it supports both endians. Let's just add an
explicit -EL to make sure it always succeeds like the kernel does.
