I tried this, with autoconf 2.61, it builds libtool, but the test 
fails, as ac_cv_prog_make_make_itx_set=no apparently isn't forwarded 
to the tests. I saw plain 'make' in the log. (attached)

I did a second test where I
- added "AM_MAKEFLAGS = $(MAKEFLAGS)" to all the Makefile.am files
- $ automake-1.10
- $ ./configure MAKE=make.itx MAKEFLAGS=-r
- $ make.itx -r
- $ make.itx -r check-local

There also are several failed tests, due to non-existent 'make'
(log not attached as it hasn't finished yet).

I now found out that! Problem seems that target "clean-ltmain-sh" 
apparently isn't marked as PHONY, and Interix make handles 
non-existent targets as both infinitely new and as infinitely old, so 
ltversion.m4 is rebuilt first, and later rerunning ./configure gets 
necessary. See the make debug log. (I didn't change and re-test, so I 
don't know if this is the only missing PHONY.)

PS: Please don't forget to update
libtool-1.5.23c/libltdl/config.{guess,sub}
before releasing 1.5.24, so that it matches the interix[3-9] change.
For 2.1a it's clever now to only have one copy of config.{guess,sub}.
