[Buildroot] [PATCH 1/1] package/boost: enable system on host

[Fabrice Fontaine]

boost system (which provides boost asio) is needed by host-riscv-isa-sim
since its addition in commit ea033cecf990ed3f86619647523a9ad2ccb09adb:

configure: error: Could not find a version of the Boost::Asio library!

Fixes:

I was wondering why we need to disable those, and the original commit
log is not very explicit about why this is so (429ffbd2253 boost: add
host variant), and the comment is not very helpful either...

So I did a test: remove all those exclusion (just exclude python [0]),
and build just host-boost (it has no dependency):

    master      : 54s
    no-exclusion: 2min 38s

So yes, this is a big increase. But considering that we have no way for
host packages to express dependencies on Boost features, I wonder if we
should not just build the whole stuff. For example, packages in a
br2-external have no way to say so...

Anyway, in the meantime: applied to master, thanks.

[0] building the Boost python module would require the python development
    files be installed on the host, or that we depend on host-python{,3},
    neither of which are acceptable

Yann E. MORIN.
