Description: add -latomic to dependencies of base component on mipsel
 This is needed to fix build of qwebengine_convert_dict, which uses the
 generated convert_dict.pri to get the list of libraries.
 .
 qmake adds its own -latomic, but it comes before the list of static
 libraries, so it does not help. We need -latomic after that list.
 .
 The error was:
 .
 /usr/bin/ld.bfd: <<BUILDDIR>>/src/core/release/obj/base/base/base_jumbo_17.o: undefined reference to symbol '__atomic_load_8@@LIBATOMIC_1.0'
 /usr/bin/ld.bfd: /usr/lib/gcc/mipsel-linux-gnu/9/libatomic.so: error adding symbols: DSO missing from command line
