[Buildroot] [git commit] trousers/tpm-tools: enable on ARC

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=a65194b3fe945e301ea7f0089186d5482a458fd9
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

With the latest ARC toolchain arc-2018.03 builds of "trousers" and
"tpm-tools" packages perform without errors.
Lets enable these packages for ARC.

With the exception, building tpm-tools for ARC770/750 requires to pass
"-mno-compact-casesi" as it was made for trousers before:
see patch f4cd8ceb9cfa "trousers: Pass "-mno-compact-casesi" when
building for ARCv1".
This change is a temporary workaround and the feature is going to be
fixed in the next ARC toolchain release version.
