Disable abs() redefinions under libc++ in devel/upp

During the exp-run in bug 208158, it was found that devel/upp gives errors with libc++ 3.8.0 [1]:

In file included from ide/BaseDlg.cpp:1:
In file included from ide/ide.h:4:
In file included from ./ide/Common/Common.h:4:
In file included from ./ide/Core/Core.h:4:
In file included from ./Esc/Esc.h:4:
./Core/Core.h:346:20: error: 'abs' is missing exception specification 'throw()'
inline UPP::int64  abs(UPP::int64 x)          { return x < 0 ? -x : x; }
                   ^
                                     throw()

This is because Core/Core.h is attempting to redefine its own versions of abs(), for int64 and double, respectively.  There is no need to do so with libc++, so add checks for _LIBCPP_VERSION to disable the redefinitions, when compiling under libc++.
