Arch Linux

Description: There are a few fixes needed for this package to build properly.
First, which depends on #35500, is to fix the include for shapefil.h to change the include from <libshp/shapefil.h> to just <shapefil.h>:
sed -i 's:libshp/::' gen2shp.c

Second, for the shapelib libshp.a library to link properly, the order in the Makefile needs to be changed with:
sed -i 's/-lshp gen2shp.c utils.o/gen2shp.c utils.o -lshp/' Makefile

Third, to include our CFLAGS in the build, run make as:
make CFLAGS="$CFLAGS"

All together it should look something like:
# fix conflicting function names
sed -i 's/getline/get_line/' gen2shp.c utils.c utils.h
sed -i 's:libshp/::' gen2shp.c
sed -i 's/-lshp gen2shp.c utils.o/gen2shp.c utils.o -lshp/' Makefile
make CFLAGS="$CFLAGS"

Additional info:
* package version: 0.3.1-8

Steps to reproduce: Build from a clean chroot.
