[Tarantool-patches] [PATCH] static build: fix build on ubuntu

[HustonMmmavr <huston.mavr@gmail.com>]

Fixed static build with '-DBUILD_STATIC=ON' option:

* Added cmake option CMAKE_DL_LIBS to icu library for
  test/unit tests binaries builds at file:
    cmake/FindICU.cmake
  due to fail:
    [ 84%] Linking CXX executable vy_point_lookup.test
    /usr/local/lib/libicuuc.a(putil.ao): In function `uprv_dl_open_62':
    putil.cpp:(.text+0x1a22): undefined reference to `dlopen'
    /usr/local/lib/libicuuc.a(putil.ao): In function `uprv_dlsym_func_62':

    /usr/local/lib/libicuuc.a(putil.ao): In function `uprv_dl_close_62':
    putil.cpp:(.text+0x1a61): undefined reference to `dlclose'
    collect2: error: ld returned 1 exit status

* Added cmake option CMAKE_DL_LIBS to gomp library for
  test/unit tests binaries builds at file:
    cmake/BuildMisc.cmake
  due to fail:
    [ 91%] Linking CXX executable bps_tree.test
