librtas: new package

[Thomas:
  - make the package depend on glibc, since it needs execinfo.h
  - use TARGET_CONFIGURE_OPTS instead of defining manually CC and LD
  - add hash file
  - remove useless empty newline.
  Thanks to Romain Naour for the review!]

+Add a line to the librtas Makefile to create librtas.so.1 when
+performing "make install".
+
+Without this patch programs linked with librtas will fail at run time:
+
+error while loading shared libraries: librtas.so.1: cannot open shared
+object file: No such file or directory
+
+A patch has been submitted upstream so it is likely that this patch
+can be dropped after the next release of librtas.
