Subject: makefiles: call GNU /bin/echo directly instead
X-Git-Url: http://sraa.de/git/?a=commitdiff_plain;h=84b2539b604e9b7781aa0bd56a09b2736b661ce2;hp=72e08f31e7589c2901158d3abdb7e116c6c6f83e;p=jump.git

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.
