Blackberry mkspecs: Refine compiler options
stack-protector-strong gives performance benefits over
stack-protector-all and is still checking more than -stack-protector,
so seems to be a good middle way and we want to use it when it is
there.
The -shared option for the compiler (not the linker) prevents a
RIM internal version of qcc from forcing -fPIE, and should not harm
in general when set.
In addition, add a method "compilerSupportsFlag" for Windows as is
present in the Unix configure script.
