GCC 5 combined with a recent binutils have a new optimization that
allows them to generate copy relocations even in -fPIE code. Clang has
the same functionality when compiling an executable with -flto. We need
to let the compilers know that they cannot use copy relocations, so they
need to use really position-independent code.
Position independent code throughout is not really required. We just
need the compilers to use position-independent access to symbols coming
from the Qt libraries, but there's currently no other way of doing that.

We've been setting the -Zm argument since the dawn of times (even before
the first git commit). Anyhow, MSDN from VS2008 onwards indicates
that this is not needed:
"In earlier versions of Visual C++, the compiler used several discrete
heaps, and each had a finite limit. Currently, the compiler dynamically
grows the heaps as necessary up to a total heap size limit, and requires a
fixed-size buffer only to construct precompiled headers. Consequently, the
/Zm compiler option is rarely necessary."
[ChangeLog][Compiler Specific Changes] Visual Studio: -Zm200 (an option to
specify the precompiled header memory allocation limit) is not added anymore
by qmake to the compiler calls. If you encounter an C1076 compiler error you
might need to re-add it in your .pro file.
