Icecream has a behavior that causes it to recompile files locally if gcc generates any warnings or errors. The reason for this is that GCC tries to re-read the input file in order to display the offending line with a caret below it, which doesn't work in the remote chroot.
Default to disabling this this workaround and add -fno-diagnostics-show-caret to the GCC flags so that errors and warnings generated by GCC do not show erroneous results. Users can override this default in the SDK by defining ICECC_CARET_WORKAROUND="1" either before or after sourcing the SDK environment.
