You can do something like this with the Lua parser:
Tupdefault.lua (at the top of your project):
tup.foreach_rule('*.c', 'gcc -c %f -o %o -I$(NETHACK_ROOT)/include',
{'%B.o', '$(NETHACK_ROOT)/<objs>'})
Tuprules.lua (at the top of your project):
NETHACK_ROOT = tup.getcwd()
Tupfile.lua (wherever you want to link everything):
tup.rule('$(NETHACK_ROOT)/<objs>', 'gcc -o %o %<objs>', 'nethack')
So three files in total, each one line.

If the files have the same name, won't you run into trouble putting
everything in $(TOP)/temp regardless?
