The Makefile has many variables influencing the build process. These can be
adjusted by modifying the Makefile.conf file which is created at the
`make config-...` step (see above), or they can be set by passing an option
to the make command directly.
For example, if you have clang, and (a compatible version of) `ld.lld`
available in PATH, it's recommended to speed up incremental builds with
lld by enabling LTO:
$ make ENABLE_LTO=1
For other compilers and build configurations it might be
necessary to make some changes to the config section of the
Makefile.
