firebird: fix CXXFLAGS

In 3.0.4, the horrible makefiles override the CXXFLAGS variable:

firebird/builds/posix/prefix.linux_generic:CXXFLAGS=-std=gnu++03

Work around that by passing LO's customised CXXFLAGS as a command-line
parameter to make, which in turn overrides the definition in the
makefile.

Other platforms, in particular Darwin, apparently extend CXXFLAGS
instead of overwriting.

To nobody's surprise, gnu++03 doesn't even build with clang because ICU
headers use C++11 features (although strangely gcc doesn't complain).
