    Better debugging in tmpfs-config-make
    
    Until now, for debugging, `tmpfs-config-make' would set `LDFLAGS'. However,
    GNU Libtool has better and higher-level enable/disable configure options
    for this job: `--disable-shared' (for this case). This way, in case the
    user needs to put some other values in `LDFLAGS', they can do it freely and
    this option is directly given to Libtool's configuration options. The
    commented explanations were also updated, inspired for the example in
    Libtool's manual (in the `Static-only libraries').

+# FOR DEBUGGING: uncomment the second half of this line. Gnuastro uses GNU
+# Libtool to build shared libraries for highly portable and maintainable
+# usage on a wide variety of systems. While this is great for binaries, it
+# can be a pain when trying to debug. For this reason, compilation of
+# shared libraries can be turned off by specifying the --disable-shared
+# option to configure. With static libraries, compilation (the `make'
+# command) will also significantly speed up. Also, by default (in
+# `configure.ac'), we have set optimization flags which have to be
+# cancelled in debugging.
