makefiles: call GNU /bin/echo directly instead

GNU echo requires the "-e" switch to handle escape sequences. Other versions
(usually shell-builtins) print out the switch or don't handle the sequences at
all. POSIX doesn't specify any behaviour, pointing to printf for consistency.

Call GNU's /bin/echo directly to pretty-print make output.
