QNX: Fix -developer-build
-developer-build enables -Werror=undef, which uncovered a bug inside
qcompilerdetection.h.
According to the Dinkum headers, it is necessary to account for three different states
concerning the values of the _HAS_* macros:
1. undefined
2. 0
3. 1
Therefore, it is necessary to check both whether it is defined and if it is
not 0. Only checking whether a given macro is 0 will generate a trap by
-Werror=undef.
(__GLIBCXX__ is the sole exception).
