Thomas Petazzoni c2ea056a1b package/qt5/qt5base: use ccache for building host code
qt5 currently doesn't use HOSTCC/HOSTCXX, so it doesn't use ccache
when building all its host code (especially qmake). This means that
even with ccache enabled and a hot cache, it still takes a long time
to build qt5base.

Before this patch, building qt5base takes:

 - 446 seconds with a cold ccache
 - 185 seconds with a hot ccache

This is because the ccache is not used for host code.

After this patch, building qt5base takes:

 - 450 seconds with a cold ccache
 - 15 seconds with a hot ccache

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
