[reposted from lfs-dev by request]
I've built GCC4-20050721 up through chapter 6 "readjusting toolchain".
When, as recommended, I compile dummy.c and running readelf -l on it,
everything appears normal, but the executable is in fact un-runnable:
[lfs chroot src]# ./a.out
bash: ./a.out: No such file or directory
[lfs chroot src]# ldd a.out
/usr/bin/ldd: line 124: ./a.out: No such file or directory
[lfs chroot src]# /lib/ld-2.3.5.so a.out
a.out: error while loading shared libraries: a.out: cannot open shared
object file: No such file or directory
[lfs chroot src]# readelf -l a.out
Elf file type is EXEC (Executable file)
Entry point 0x80482b0
There are 7 program headers, starting at offset 52

I've been unable to track down what's wrong. The host system is
Debian-testing. For what it's worth:

There were some probably unrelated errors in the glibc testsuite:
