what is your version of glib? in the version i have installed
(dev-libs/glib-2.28.8) it is a macro in gthread:

# grep g_thread_supported /usr/include/glib-2.0/glib/gthread.h
 * g_thread_supported macro but provided for language bindings.
    (g_thread_supported () ? G_THREAD_UF (op, arg) : (fail))
    (g_thread_supported () ?
						\ (g_thread_supported
() ? ((void(*)(GCond*, GMutex*, gulong, gchar*))\ (g_thread_supported
() ?						\ #define
g_thread_supported()     1 #define g_thread_supported()
(g_threads_got_initialized)

an a macro is not a function you can link to compiled into the library:

# nm /usr/lib64/libgthread-2.0.a | grep g_thread_supported

that would explain why linking against it doesn't work.

maybe that changed in newer versions of glib?
