ci: fix the executable file report

[illwieckz]

Fix the executable file report.

[illwieckz]

This “test” isn't blocking, but is useful when reading logs.

Before:

+ EXECUTABLES='crunch example1 example2 example3'
+ for exe_file in ${EXECUTABLES}
+ file 'build/${exe_file}${CRUNCH_EXTENSION:-}'
build/${exe_file}${CRUNCH_EXTENSION:-}: cannot open `build/${exe_file}${CRUNCH_EXTENSION:-}' (No such file or directory)
+ for exe_file in ${EXECUTABLES}
+ file 'build/${exe_file}${CRUNCH_EXTENSION:-}'
build/${exe_file}${CRUNCH_EXTENSION:-}: cannot open `build/${exe_file}${CRUNCH_EXTENSION:-}' (No such file or directory)
+ for exe_file in ${EXECUTABLES}
+ file 'build/${exe_file}${CRUNCH_EXTENSION:-}'
+ for exe_file in ${EXECUTABLES}
+ file 'build/${exe_file}${CRUNCH_EXTENSION:-}'
build/${exe_file}${CRUNCH_EXTENSION:-}: cannot open `build/${exe_file}${CRUNCH_EXTENSION:-}' (No such file or directory)
build/${exe_file}${CRUNCH_EXTENSION:-}: cannot open `build/${exe_file}${CRUNCH_EXTENSION:-}' (No such file or directory)

After:

+ EXECUTABLES='crunch example1 example2 example3'
+ for exe_file in ${EXECUTABLES}
+ file build/crunch
