This commit modifies the toolchain-wrapper to make sure that the CCACHE_COMPILERCHECK and CCACHE_BASEDIR are only set if ccache support is enabled. Indeed, when BR2_USE_CCACHE is not set (or to a value different than 1), we don't call the compiler with ccache, so there is no reason to set those ccache environment variables, and they could potentially conflict with a separate usage of ccache, outside of Buildroot, for example when using the Buildroot SDK. In particular, the value of CCACHE_BASEDIR doesn't not make any sense when the Buildroot toolchain is not used during the Buildroot build, as it points to the output directory $(BASE_DIR). We pay attention to also not show those variables as being set in the BR2_DEBUG_WRAPPER dump. To help a little bit with this, a ccache_enabled boolean is introduced to indicate when ccache is being used. There is still quite a bit of #ifdef-ery involved, but it's not easy to find a simpler way to organize the code.

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 OFTC IRC.
