This patch is replaces two previous sumbissions, the first by Bernd Kuhls [1],
the second by me [2].
The posix_memalign declaration is incompatible with musl for C++ on x86, because
of the exception specification [2]. Note, the referenced patch is part of a
patch series to "Add musl support to GCC".
However, this build issue only happens if compilation is done with the GCC
compiler option '-pedantic' [3] which is done so in jsoncpp.
Fortunately, upstream accepted a patch to opt-out '-pedantic' [4]. We backport
this patch to fix autobuild errors.
