libXbgi is a Borland Graphics Interface (BGI) emulation library for
X11. This library strictly emulates most BGI functions, making it
possible to compile X11 versions of programs written for

Less Makefile code, pkgconfig is used, libXbgi can be built as a
shared library.

xbgi: resolve invocation of undefined behavior in grapherrormsg.c

Summary:
The value of errormsg is undefined. In particular, it is not
even guaranteed to have enough space to hold the strings copied
into it with strcpy.
Switch to constant string pointers.
