Subject: libnewt.pc: add data for static linking


With this patch I can statically link a binary with libnewt without listing
the required libraries manually:

gcc -o test_static test.c `pkg-config --libs --cflags --static libnewt`

Without this patch static linking fails due to multiple undefined
references:

/usr/bin/ld: /tmp/test.AcRBJp.ltrans0.ltrans.o: in function `buttonDrawIt':
