>Description:
gcc by default looks in PREFIX/include for header files, regardless of
whether -IPREFIX/include is specified. This severely breaks buildlink2
because all header files in PREFIX/include are available to the
compiler, causing some package builds to fail.

An example of this is devel/gdb, which cannot be built with lang/gcc if
devel/ncurses is installed due to conflicting header files.

A possible workaround is to set CFLAGS=-nostdinc -I/usr/include, but
this is ugly.
>How-To-Repeat:
# ls -l /usr/pkg/include/ncurses.h
-r--r--r--   1 root     root       55879 Apr  8 02:41 /usr/pkg/include/ncurses.h
# cat blah.c
#include <ncurses.h>

main () { }

# /usr/pkg/bin/gcc -c blah.c
#
>Fix:
hack the gcc pkg to not look in PREFIX/include.
