New issue 175 by rco...@il4p.fr: m4 macro is not able to auto-detect
readline in cross-compiling environnement
http://code.google.com/p/libnfc/issues/detail?id=175

What steps will reproduce the problem?
1. Use a cross-compiling development
2. Attempt to build libnfc with pn53x-tamashell (which use readline)

What is the expected output? What do you see instead?
readline should be correctly detected but it use the host's files instead
of the target ones.

auto-detect readline in cross-compiling environnement

As first workaround, you could disable readline support (will affect only
pn53x-tamashell) using the configure option:

./configure --with-readline=no

You could also pass directly the path where the target's readline is
located: e.g.
./configure --with-readline=/path/to/the/toolchain/usr

(In this case, please be sure that readline is located in lib/ and include/
subdirs)

See r1177
This should ease the job...
readline support is now disabled when cross-compiling unless you specify
full path to host libraries (--with-readline=/path/to/the/toolchain/usr)
