[Buildroot] [PATCH] package/clapack+armadillo: re-enable on MIPS

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

From: Thomas De Schampheleire <thomas.de_schampheleire@nokia.com>

Commit d2b52cebf3b8b4a922a54d38a44a8a183406c5f1 disabled clapack on MIPS
platforms, to fix an autobuild failure (unfortunately, the results are no
longer available). The argument was:

    "Disable this package for MIPS because it needs IRIX headers and
    libraries."

Nevertheless, today compilation on MIPS seems to work fine. Testing was done
with test-pkg (armadillo depends on clapack):

$ echo "BR2_PACKAGE_ARMADILLO=y" > config.snippet;
$ utils/test-pkg -p armadillo -a -c config.snippet
                 br-mips32r6-el-hf-glibc [1/8]: OK
                      br-mips64-n64-full [2/8]: OK
                 br-mips64r6-el-hf-glibc [3/8]: OK
                      br-mipsel-o32-full [4/8]: OK
             mips64el-ctng_n32-linux-gnu [5/8]: OK
             mips64el-ctng_n64-linux-gnu [6/8]: OK
                         sourcery-mips64 [7/8]: OK
                           sourcery-mips [8/8]: OK
8 builds, 0 skipped, 0 build failed, 0 legal-info failed

Manual build tests were also done for mips32r2 with gcc 4.9.x and gcc 7.x,
and for M5150 with gcc 7.x (Buildroot-built toolchains in these three
cases).

Also building and running on Octeon III, using the toolchain provided by
Cavium Networks / Marvell, works fine.

Not seeing any problem (but also not understanding the original problem),
re-enable clapack (and armadillo) on MIPS.  If any problems would pop up in
the future, they should be investigated in detail and a more fine-grained
solution should be taken than disabling on MIPS altogether.
