Subject: makefile: switch from $() to backticks
X-Git-Url: https://git.codecow.com/?a=commitdiff_plain;h=f1f4082420f48f09d2225be7d419b21c109f40c9;p=Monocypher.git

makefile: switch from $() to backticks

This fixes building with gmake on Solaris 10,
and likely some other platforms with /bin/sh before POSIX standardized
$() for command substitution.

Addresses issue #120.
