This could be a Debian specific problem.
The failure was also observed on another Debian system.
(Which again is a cross between the current stable release, squeeze,
and the next version.)
I looked for crt1.o in supplied debian packages.
The following command prints out
the matched file names provided in each Debian package.
ishikawa <at> debian-vbox-ci:~$ dpkg --search "crt1.o"
libc6-dbg: /usr/lib/debug/usr/lib64/Scrt1.o
libc6-dbg: /usr/lib/debug/usr/lib64/crt1.o
libc6-dbg: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o
libc6-dbg: /usr/lib/debug/usr/lib/i386-linux-gnu/Mcrt1.o
libc6-dev: /usr/lib/i386-linux-gnu/Scrt1.o
libc6-dbg: /usr/lib/debug/usr/lib/i386-linux-gnu/gcrt1.o
libc6-dbg: /usr/lib/debug/usr/lib64/Mcrt1.o
libc6-dbg: /usr/lib/debug/usr/lib64/gcrt1.o
libc6-dev: /usr/lib/i386-linux-gnu/Mcrt1.o
libc6-dev: /usr/lib/i386-linux-gnu/gcrt1.o
libc6-dev: /usr/lib/i386-linux-gnu/crt1.o
libc6-dbg: /usr/lib/debug/usr/lib/i386-linux-gnu/Scrt1.o
So they are all from libc6-dev, and libc6-dbg.
I got curious and checked the intallation status of libc6 on the computer.
Looks they are installed alright. See below
$ aptitude search libc6

p libc6-amd64 - Embedded GNU C Library: 64bit

Lines that start with "i" in the first column mean the package on the
line are currently installed.
I wonder, though, why simple libc6 (not -dev, not -dbg) doesn't have
crt1.o according to the output of "dpkg --search".
Maybe emacs should not look at crt1.o?
At least not on the next Debian distribution currently in testing status?
The debian distribution on the PC I use is halfway across from
squeeze, the current stable version, to the next planned main release
version, w...something. I hate the clever naming.
GCC seems to have beeen installed without a problem. It can compile
emacs after the aforementioned additional parameter to configure. It
can compile VirtualBox support modules for linux: I run this instance
of linux inside VirtualBox environment. So the installation of GCC is
complete as far as I can tell. (The other computer where emacs
configure without --with-crt-dir failed also has gcc
installed. It can compile and link mozill's thunderbird, a very
complex program, indeed. So GCC installation there is complete also.)
By the way, I diff'ed ./configure under 23.3 and 23.3 and didn't find
much change as far as CRT_DIR is concerned , so assume that it is not
that different. So the cause seems to be a different packaging and
layout of libc6 under (newer) Debian packages.
I checked the time-stamp of the binary of emacs 23.3 which I compiled
myself on my PC and have been using. emacs-23.3 compiled fine last
May (May 2011) when I used then current Debian distribution. So the
Debian packaging has changed between the current stable and the next
version (testing) since then.
Fix?
My suggestion is to move the test for the validity of CRT_DIR after
the case statement (and after the default setting of CRT_DIR). See
patch and the execution of configure below. [Currently, it is tested
only inside the case statement for 64 bits checking. No checking is
done outside the case statement.]
Then, at least, the missing crt1.o is noticed immediately during the
configure before make is invoked.
