# In other projects we specify the sysroot location using CPPFLAGS.
# Here, that breaks because GCC compiles stuff for the *build* machine,
# too ... and this requires using the host's compiler, which cannot use
# the same set of CPPFLAGS as the target. If we specify the sysroot
# using CC instead then we don't interfere, because we are only
# specifying the *host* C compiler.
#
# Configure flag notes:
# 1. It's vital that this compiler runs in the bootstrap machine, and
# targets the same machine (TARGET_STAGE1) so that the stage 1 GCC
# is used instead of the compiler of the build machine.
# 2. See gcc.morph.
# 3. Disable searching /usr/local/include for headers
# 4. This flag causes the correct --sysroot flag to be passed when
# calling stage 1 GCC.
