# llvm libc math tests reply on `mpfr`.
# The availability of `mpfr` is controlled by a flag and can be either `disable`, `system` or `external`.
# Continuous integration uses `system` to speed up the build process (see .bazelrc).
# Otherwise by default it is set to `external`: `mpfr` and `gmp` are built from source by using `rules_foreign_cc`.
# Note: that building from source requires `m4` to be installed on the host machine.
# This is a known issue: https://github.com/bazelbuild/rules_foreign_cc/issues/755.
