[patch] Don't add PTH include path to gpgme's CFLAGS globally

[Michael Nottebrock]

In FreeBSD 6 and later, sys/types.h now also defines the basic pthread types 
in order to comply with IEEE Std 1003.1-2004.

This causes a compile error in gpgme due to conflicting types for pthread_* if 
pth-support is enabled, since the pth include directory is globally added to 
CFLAGS and ath-pthread.c picks up the pth-supplied pthread.h header instead 
of the system include:

cc -DHAVE_CONFIG_H -I. -I. -I.. -I../assuan -I/usr/local/include 
-I/usr/local/include/pth -I/usr/local/include/pth 
-I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include -O2 
-pipe -O2 -fno-strict-aliasing -Wall -Wcast-align 
-Wshadow -Wstrict-prototypes -MT ath-pthread.lo -MD -MP -MF 
.deps/ath-pthread.Tpo -c ath-pthread.c  -fPIC -DPIC -o .libs/ath-pthread.o

The attached patch changes the Makefile template in the gpgme subdir so that 
PTH_CFLAGS are only added to the include path where needed.
