--debug-configure doesn't quite work

[David Holmes]

Okay some weird happened with piping the output into tee. But I got past 
that and then hit this :)

++ files_present='confdefs.h
config.log
debug-configure.log'
+++ /bin/echo 'confdefs.h
config.log
debug-configure.log'
+++ /bin/sed -e s/config.log//g -e s/confdefs.h//g -e 's/ //g'
+++ /usr/bin/tr -d '\n'
++ filtered_files=debug-configure.log
++ test xdebug-configure.log '!=' x
++ printf '%s\n' 'configure:7991: Current directory is 
/java/embedded/users/dh198349/build-infra/builds/b00/se-linux
t-ea.'
++ printf '%s\n' 'configure: Current directory is 
/java/embedded/users/dh198349/build-infra/builds/b00/se-linux.
'
configure: Current directory is 
/java/embedded/users/dh198349/build-infra/builds/b00/se-linux.
configure: Since this is not the source root, configure will output the 
configuration here
configure: (as opposed to creating a configuration in 
<src_root>/build/<conf-name>).
configure: However, this directory is not empty. This is not allowed, 
since it could
configure: seriously mess up just about everything.
configure: Try 'cd /java/embedded/users/dh198349/build-infra' and 
restart configure
configure: (or create a new empty directory and cd to it).

----

Oops! The debug log causes configure to stop configuring. Simple patch 
below:
