You can allways set the $CFLAGS environment variable before runnig configure,
but it doesn't seem to be mentioned anywhere.

I second this.  I learned about existence of externals only when editing
lynx.cfg,  and even there there is no mention of the fact that it works only
when lynx is compiled with -DUSE_EXTERNALS.  I had to search changes file to
find out.  I don't know how many sysadmins are going to do that when
installing lynx on their systems.

I suggest:

1) adding a line or two in lynx.cfg about it,  something similar as for
   LONG_LIST or EXP_CHARTRANS.

2) add USE_EXTERNALS either into userdefs.h or docs/README.defines.  In the
   later case,  add a line to INSTALLATION about reading the
   docs/README.defines before running configure.

3) possibly creating a configure option,  something like --enable-externals.
   Add something like this in configure.in:

   AC_MSG_CHECKING(if EXTERNALs should be used)
   AC_ARG_ENABLE(externals, [  --enable-externals enable use of EXTERNAL
   command in lynx.cfg], [AC_DEFINE(USE_EXTERNALS)])
   AC_MSG_RESULT($enableval)
