I just thought of an alternative. What if program searching did NOT insert the 
directory path in front? At least if the path includes a space and the 
directory is part of the PATH?  Seems to me that AC_CHECK_PROG could be 
modified to allow something like this as this as an option.

E.g. when using AC_CHECK_PROG to search for "sbcl", the generated makefile 
would say:
SBCL = sbcl

This introduces security/reliability issues and also hazards if one of the build products was called 'sbcl' or if PATH is updated as part of the build/test process.

Do you know what the output of AC_CHECK_PROG is used for? If you don't know the answer, then the output should not be changed.

I do know that this would cause reliability/security problems for the package I maintain.
