Subject: [PATCH] Add dl to pkg-config metadata

This simplifies compiling by allowing users to include

   CFLAGS += `pkg-config --cflags erasurecode-1`
   LDFLAGS += `pkg-config --libs erasurecode-1`

in makefiles. Otherwise, trying to use pkg-config results in errors like

   /usr/local/lib/liberasurecode.so: undefined reference to `dlopen'
   /usr/local/lib/liberasurecode.so: undefined reference to `dlclose'
   /usr/local/lib/liberasurecode.so: undefined reference to `dlerror'
   /usr/local/lib/liberasurecode.so: undefined reference to `dlsym'
   collect2: error: ld returned 1 exit status
