[LTP] [RFC PATCH 2/2] travis: Update params for build.sh + change builds

[Petr Vorel]

Add powerpc64le cross-compile build.
Some builds set to be out-of-tree or minimal.

We now have 10 builds, some combination of:
5x native + 2x 32-bit + 3x cross-compile
5x in-tree + 5x out-of-tree
7x full dependencies + 3x minimal dependencies

Using compilers:
gcc 4.9, 5, 6, 7,
clang 3.9, 4, 5
gcc (cross-compile): 3x 4.8.4
cross-compile archs: arm, aarch64, powerpc64le
