_LT_ENABLE_FAST_INSTALL being expanded multiple times.

[Peter O'Gorman]

Hi,

When building ImageMagick on Mac OS X, and installing with DESTDIR
Jochem Huhmann of the MacPorts project noticed that the wrapper scripts
were being installed, and the binaries not.

I expect on darwin that fast_install always be set to needless,
eliminating the need for relinking, however, with libtool HEAD, it gets
set to needless, then if your configure.ac contains both LT_INIT and
next LTDL_INIT, it gets set back to 'no' again.

Both LT_INIT and LTDL_INIT expand _LT_SET_OPTIONS, which duly expands
_LT_ENABLE_FAST_INSTALL *twice*.

_LT_SET_OPTIONS should only set the default options once (and only for
LT_INIT).

Peter
