# Configure flag notes:
# 1. Location of linux-api-headers, needed since glibc doesn't
# support being given a sysroot.
# 2. Location of binutils, since we build binutils for the final
# target triplet, but our gcc of our stage 1 target triplet.
# 3. Normal flags. See strata/build-essential/glibc.morph.
# 4. Force configuration values of certain things that can't be detected
# in a cross-compile.
