Makefile: Try making a release build with ECL

Wanted to try using ECL to build a smaller executable.

The commented section is adapted from the SBCL build command in the
`build` target. Didn't work, the build errored with the following:

    An error occurred during initialization:
    Unable to create pipe
    C library explanation: Too many open files..
    ext::getcwd error: Too many open files

    Internal or unrecoverable error in:
    Can't work without CWD
      [24: Too many open files]

The second build command comes from:
https://gitlab.com/embeddable-common-lisp/ecl/-/tree/6a5dea52/examples/asdf_with_dependence

That one compiled without errors, but resulted in the following runtime
error:

    $ ./extreload

    Condition of type: SIMPLE-ERROR
    The packages
      ((UIOP/OS . #<UIOP/OS package>) (UIOP/PATHNAME . #<UIOP/PATHNAME package>))
    were referenced in compiled file
      NIL
    but have not been created
    Available restarts:

    1. (IGNORE) Ignore the error, and try the operation again

    Top level in: #<process TOP-LEVEL 0x1045acf80>.
