# 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.
