That symbol isn't related to libproj; the fact that it begins with a
dot suggests something internal.

I note that all of the errors refer to PJ_krovak.o and PJ_krovakgis.o. 
The most obvious difference between these two files and all of the
others in libproj is that they include <stdio.h> and <string.h>, and
they do so after they have included "projects.h".

AFAICT, those headers are only used by some debug code which is
disabled. I suggest changing the top of each of those files from:

	#include "projects.h"
	#include <string.h>
	#include <stdio.h>

to just:

	#include "projects.h"

Contrary to my previous guess, this *isn't* a problem with your GD
library; the display drivers themselves need the math library (for
drawing rotated text), but the Gmakefile for PNGdriver doesn't specify
it.

In src/display/devices/PNGdriver/Gmakefile, change line 29 from

	$(CC) $(LDFLAGS) -o $@ $(OFILES) $(LIBES) $(XDRLIB) $(GDLIB)
to:
	$(CC) $(LDFLAGS) -o $@ $(OFILES) $(LIBES) $(XDRLIB) $(GDLIB) $(MATHLIB)
