# OCaml >= 4.08.0 uses an autotools-based build system. In this case we
# convince it to think it's using the Solo5 compiler as a cross compiler, and
# let the build system do its work with as little additional changes on our
# side as possible.
#
# Notes:
#
# - CPPFLAGS must be set for configure as well as CC, otherwise it complains
# about headers due to differences of opinion between the preprocessor and
# compiler.
# - ARCH must be overridden manually in Makefile.config due to the use of
# hardcoded combinations in the OCaml configure.
# - We use LIBS with a stubbed out solo5 implementation to override the OCaml
# configure link test
# - We override OCAML_OS_TYPE since configure just hardcodes it to "Unix".
