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.
