mkheaders.in uses substitutions of @SHELL@ to run fixinc.sh and mkinstalldirs. Problem is, SHELL comes from CONFIG_SHELL for the build system, and it needs not match whatever is available at an unrelated host system after installation, when mkheaders is supposed to be run. I considered ditching the hardcoding altogether, but decided to retain it, but allowing CONFIG_SHELL and SHELL to override it, if any of them can successfully run mkinstalldirs, and if those and the substituted @SHELL@ fail, fallback to /bin/sh and to plain execution of the script, which appears to enable at least one shell on a system that doesn't typicall have a shell to recognize a script by #!/bin/sh and reinvoke itself to run it. If all of these fail, we fail, but only after telling the user to retry after setting CONFIG_SHELL, that fixincl itself also uses. for fixincludes/ChangeLog * mkheaders.in: Don't require build-time shell on host.
