BUILD: Fix linking with librt
The posix realime extensions defines timer_* functions
but it does not mention library with these functions.
http://www.unix.org/version2/whatsnew/realtime.html
The autoconf macro AC_SEARCH_LIBS firstly check the function
timer_create with no libraries, then for each library listed
in 2nd parameter. Possible libraries librt and libposix4
were used in nspr for similar detection.
