The LDFLAGS did the magic, thank you!

Now my config.log ends with

#define EMACS_CONFIG_FEATURES "XPM JPEG TIFF GIF PNG RSVG IMAGEMAGICK SOUND
DBUS GCONF GSETTINGS NOTIFY ACL LIBSELINUX GNUTLS LIBXML2 FREETYPE LIBOTF
XFT ZLIB TOOLKIT_SCROLL_BARS GTK2 X11"

(I wonder why setting the $LD_LIBRARY_PATH and $PKG_CONFIG_PATH env vars
did not help.)

Here's my emacs build csh script in the case it could be helpful to someone:

#!/bin/tcsh -f
# emacs build script for non-root users (tested to work for RHEL 6)

# Usage: source mybuild.csh <VERSION or BRANCH>
# Example: source mybuild.csh emacs-24
#          source mybuild.csh master
# For RHEL 6, do "setenv MY_OSREV 6"
# ${HOME}/usr_local/${MY_OSREV} is the directory that I use as --prefix for
building libraries locally when the default library does not exist or is
older than the requirements
# I already have the env vars PATH, LD_LIBRARY_PATH, PKG_CONFIG_PATH and
INCLUDE_PATH to include the respective directories
${HOME}/usr_local/${MY_OSREV}
# Ensure that PKG_CONFIG_PATH has /usr/share/pkgconfig for xproto.pc and
related files. This is necessary for XFT and related X11 features..
otherwise the fonts will look horrible.
