feature/native-comp c35a515: Fix install with NS app bundle

[Alan Third]

branch: feature/native-comp
commit c35a515a2f7045f004299f601f6d1927ea16cd47
Author: Alan Third <alan@idiocy.org>
Commit: Alan Third <alan@idiocy.org>

    Fix install with NS app bundle
    
    * configure.ac: Set up CFLAGS and LDFLAGS to find a Homebrew
    installation of libgccjit.
    * Makefile.in (ELN_DESTDIR): Set to the app bundle resource dir when
    required.
    (install-eln): macOS install doesn't support the -D flag, so make the
    directories separately.
