package/boost: disable boost-locale for static only build with icu

Browse Source 
Boost fails to build with the following error:

error: Tried to build the target twice, with property sets having
error: these incompatible properties:
error:
error:     -  <runtime-link>static <warnings>all
error:     -  <runtime-link>shared <warnings>on

when the following conditions are met:

 - BR2_STATIC_LIBS=y
 - BR2_PACKAGE_ICU=y
 - BR2_PACKAGE_BOOST_LOCALE=y
 - Another BR2_PACKAGE_BOOST_xyz option is enabled, which enables a
   feature not provided just by header files, but that requires
   building a library.

In such a situation, Boost absolutely wants to build the libboost
libraries as shared libraries. Not having boost-locale, or not having
icu is sufficient to avoid the issue.

So, as a simple work-around, we prevent from building boost-locale
when icu and static linking are used.

Fixes:

# When boost-locale is enabled with icu support, Boost no
# longer supports building the libboost_* libraries as static
# libraries, causing build failures when other boost features
# than boost-locale are enabled. To work around this, we
# prevent using boost-locale on static linking configurations
# with icu enabled. See
