Subject: modules: do not include gmodule-2.0 in static builds
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~1045
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=aa0d1f448871314bfc535da97eb003fe7766d4c2;p=sdk%2Femulator%2Fqemu.git

modules: do not include gmodule-2.0 in static builds

gmodule-2.0's pkg-config files include -Wl,--export-dynamic, which breaks
static builds.  It is a glib bug, but we need to support --static builds for
the linux-user targets, and in the end all that is needed to fix this is:

* outlaw --enable-modules --static, which makes little sense anyway

* only include gmodule-2.0's cflags and ldflags if --enable-modules is
specified on the command line.
