Subject:  * check if dlopen() is in libc first, then in libdl
X-Git-Tag: accepted/2.0/20130306.224007~195^2~305
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=60f2ca154c913b8e99a617321e7e6ca2b50f844a;p=profile%2Fivi%2Fecore.git

 * check if dlopen() is in libc first, then in libdl
 * check if clock_gettime() is in libc first, then in librt

some systems have these functions in libc, or in a specific lib.
This allows to correctly set dlopen_libs and rt_libs variables.
