A bit premature here.  I quickly ran ./configure before work and
configure worked OK.  But tonight, run make, my linker bombed out with:

/usr/lib/gcc/i486-slackware-linux/4.8.2/../../../../i486-slackware-linux/bin/ld:
cannot find
-libmbedtls /usr/lib/gcc/i486-slackware-linux/4.8.2/../../../../i486-slackware-linux/bin/ld:
cannot find
-libmbedx509 /usr/lib/gcc/i486-slackware-linux/4.8.2/../../../../i486-slackware-linux/bin/ld:
cannot find -libmbedcrypto

Strange, as ldconfig -v reveals:

/usr/local/lib:
	libmbedcrypto.so.0 -> libmbedcrypto.so.2.3.0
	libmbedtls.so.10 -> libmbedtls.so.2.3.0
	libmbedx509.so.0 -> libmbedx509.so.2.3.0

Anyway, an hour of investing, it turns out the linker flags are
incorrect - changing in configure fixed it up:

  if test "x$ssl_ok" = "xyes"; then
    LIBSSL_LIBS="-libmbedtls -libmbedx509 -libmbedcrypto"

Should be -lmbedtls, -lmbedx509 and -lmbedcrypto

All really does build fine now :)

mbedtls seems to work well - seems a tad quicker too.
