Enhance automake now for BLFS later

[John Coleman]

It would be REAL NICE if the install instructions mentioned creating the 'dirlist' file in /usr/share/aclocal. XORG's xkeyboard-config wouldn't install without me copying that file from my old HDD to the new one.

If you are going to deviate from the instructions in the book, you really should be aware of the consequences prior to making any changes. If you did not make changes, then something else has happened that has left configure with an earlier timestamp than one of the auto* files. Did you verify MD5s? There is currently nothing in the book (as written) that requires this.

With that said, however, there will actually be some use cases in the Gnome section that depend on the requested change (when changing for the /opt/gnome installation). Actually, I could just diff configure and go, but it'd be nice to show it in the book using the correct method.

Something to the effect of the following example for Xorg should be added to the introduction sections for the respective distributions if being built in the optional prefixes:

echo "$XORG_PREFIX/share/aclocal" >> \
    /usr/share/aclocal/dirlist

At the risk of overstating the obvious...

For Gnome:

echo "$GNOME_PREFIX/share/aclocal" >> \
    /usr/share/aclocal/dirlist

And for KDE:

echo "$KDE_PREFIX/share/aclocal" >> \
    /usr/share/aclocal/dirlist

If there are xorg, gnome, or kde changes needed, they should go in the relevant section of BLFS. This isn't an appropriate change for LFS.
