# Configure flag notes:
#  1. Standard flags. See gcc.morph.
#  2. Our binutils is for the final $TARGET, rather than the intermediate
#     target our GCC is being built for, so we need to set
#     with-build-time-tools to get it to find our binutils at
#     build-time and with-as and with-ld so our temporary GCC uses
#     the appropriate tools when it compiles our libc, rather than
#     trying to use $TARGET_STAGE1-as when producing binaries.
#  3. Disable stuff that doesn't work when building a cross compiler
#     without an existing libc, and generally try to keep this build as
#     simple as possible.
