Overview

Ruby buildsystem patches (pass2)

COMMON_MK_PATCH =

This patch forces rebuild of extinit.c when exts.mk changes exts.mk changes when we rebuild extensions to make them statically linked [TODO] it is possible that we can build extensions statically on pass1 and it will eliminate the need for this patch

This patch changes libraries that are used for Ruby linking MAINLIBS is patched elsewhere (not with literal but dynamically) to haold the list of sattic libraries and related options Also we have to put LIBRUBYARG_STATIC instead of LIBRUBYARG to link with static libruby, configure's --disable-shared option does not do it Several variants depending on os and version
