I've looked, policy CMP0004 will not work in this situation. If you are
concatenating lib strings, then whitespace at the end of a string is an absolute
'requirement' in order to prevent that same error we see here.
LIBS=" -lm -lattr -lsane "
LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,--hash-style=gnu"
If you remove leading/trailing whitespace from ${LIBS} and concatenate
${LDFLAGS}${LIBS}, then yes, it will cause this error every time :)
