Traditionally, RCC in "C mode" was meant to bundle small resources into
a binary, like help texts or an occasional icon. RCC produces a .cpp
file containing the actual data in a char array which is then passed
to the compiler and linker as a normal source file. Larger resources
should be compiled in RCC's binary mode and loaded at run time.
Current Qt Quick use tries to deploy large hunks of data in "C mode",
causing heavy compiler/system load.
This patch works around the issue by splitting the process into
three parts:
1. Create a C++ skeleton, as usual, but use a placeholder array
with "easily compilable" (mostly NULs) data instead.
2. Compile the skeleton file.
3. Replace the placeholder data with the real binary data.
time (qmake5 ; make clean ; make) takes 1.3 s real time for a
100 MB resource here, and there is still room for improving patching
performance if really needed.

unlike the .command, the .depend_command is not executed by make via its
chosen shell, but qmake itself via the system's native shell.
consequently, it needs different path separators and no make-escaping.

And enable this configuration option for the resource compiler. This
results in a re-run of qmake whenever you touch a qrc file, which is
needed to keep the dependencies up to date. Otherwise you might end
up in the situation where you add a file to a qrc, edit the file some
time later, but a rebuild does not regenerate a cpp file and compile
that, so the final binary is stale.
Technically this dependency problem is present for all source files,
and qrc files are no different than any cpp file that you add a new
header #include to, or adding a Q_OBJECT macro to a header. To pick
up these changes we have to re-run qmake, so that qmake can run its
internal dependency checking, and any extra compiler dependency
commands.
The reason we're making this change for rcc files it that conceptually
people treat them as a "project" files, and expect them to behave similarly
to .pro or .pri files, in that editing the file will invalidate the
makefile. In practice this is often what happens when adding new
headers, as you touch the project file when changing the HEADERS
variable.
