On Ubuntu Quantal, ncurses is indeed compiled with tinfo as a separate
lib, but these two patches are not needed, because libncurses has proper
(NEEDED) on libtinfo:

  $ readelf -d /lib/x86_64-linux-gnu/libncurses.so.5.9 |grep tinfo
  0x0000000000000001 (NEEDED)             Shared library: [libtinfo.so.5]

If I just configure ncurses with:
  $ ./configure --with-termlib --with-shared --without-normal && make
  $ readelf -d lib/libncurses.so.5.9 |grep tinfo
  0x0000000000000001 (NEEDED)             Shared library: [libtinfo.so.5]

I wonder how you configured your ncurses.

But anyway, even in that cse, using pkg-config when available is better
than using our previous legacy checks.

I'm still doing a few more tests on my side before queuing.

Thanks for staying around during the iterations.
