[Buildroot] [git commit branch/2017.11.x] package/kmsxx: don't install static libraries when BR2_SHARED_STATIC_LIBS=y

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=fe3ac2c20aef525e51ff425f8acbb14f9b7a9334
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.11.x

The kmsxx build system can only build either shared libraries *or*
static libraries, not both. Therefore, the build currently fails when
BR2_SHARED_STATIC_LIBS=y because we try to install the static
libraries, that haven't been built.

We fix this by not installing the static libraries when
BR2_SHARED_STATIC_LIBS=y, making BR2_SHARED_STATIC_LIBS=y essentially
the same as BR2_SHARED_LIBS=y for this package.

Fixes bug #10331.
