Are you using parameters or environment variables with make?
I've never compiled torcs this way. 
No: ( make TORCS_BASE=/home/user/torcs-1.3.7 MAKE_DEFAULT=/home/user/ )
Yes: ( make )

run ./configure with parameters from within the torcs/ directory
then run 'make' without parameters.

eg.
./configure --prefix=/home/dooseop/local
make
make install
make datainstall
...

`png_set_longjmp_fn' is Not supposed to be part of the build for Linux.
( It is part of the Windows(tm) build )

I discovered this by grep'ing TORCS sources:

$ find . -type f -print0 | xargs -0 grep -I png_set_longjmp_fn
./src/windows/include/png.h:PNG_EXPORT(8, jmp_buf*, png_set_longjmp_fn, (png_structp png_ptr,
./src/windows/include/png.h:      (*png_set_longjmp_fn((png_ptr), longjmp, sizeof (jmp_buf)))
$
