comptools: add make-3.81

Since the advent of make-3.82, some packages now break due to changes
in make-3.82, being stricter than 3.81 when interpreting the Makefiles.

This has bugged us a bit too much so far, and I believe fixing all
of them is a long road, while simply building make-3.81 is the easiest
route for now.

Of course, in the long term, packages will get fixed upstream, and we
should back-port the fixes to old versions, and get rid of building
make-3.81. In the meantime...

Reported several times on the mailing list.

     4 This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,
     5 MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.5.1,
     6 for e500v2 DPFP support) and will generate appropriate dual-precision
     7 floating point instructions by default.

     9 Note: If building a Linux kernel with this toolchain, you will want to make
    10 sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions
    11 from getting into the kernel (which is currently unsupported). At this time,
    12 the kernel build system properly passes those two options, but older kernels
    13 were only passing -mno-spe by default."
