Marcin Bukat beef52c5f0 mipsel-rockbox-linux toolchain build fix
If we use mips-rockbox-linux target resulting toolchain is
big endian. If we use mipsel-rockbox-linux build fail since
linux doesn't have separate archs for BE and LE mips. So we
tweak arch passed to linux-headers stage to fix this.

# AGPTek Rocker:
# XBurst release 1 (something inbetween mips32r1 and mips32r2)
# gcc: 4.9.4 is the latest 4.9.x stable branch, also the only one that
# compiles with GCC >6
# kernel: 3.10.14
# glibc: 2.16
#
# To maximize compatibility, we use kernel 3.2.85 which is the lastest
# longterm 3.2 kernel and is supported by the latest glibc, and we
# require support for up to glibc 2.4
# We use a recent 2.26.1 binutils to avoid any build problems and
# avoid patches/bugs.
