it's really confusing, there is no X-I command on the system in any means, somebody said it's kind of libtool bugs, and if i substitute $echo to be $ECHO, the build will be ok:(
the unbelievable thing is that after i substitute $echo to be $ECHO, run make lib, then that libtool will recover, and all $ECHO will be $echo again, and the build failed with same error....
so how to build this package without error? any suggestions?
the package name is skyeye, it's kind of simulator, you can run many kinds of embeded system on it:) you can get the source code from
git://skyeye.git.sourceforge.net/gitroot/skyeye/skyeye
the build tutorial is here：

Recently I've had the same problem.
This is a bug in the script libtool that tries to execute the parameters (prefixed with X) as if there were programs, unless the variable $echo is defined.
To fix it, execute this before:
export echo=echo
Then try again.
Found here: I've found the solution in this thread: http://www.wreckedgames.com/forum/index.php?topic=1135.0

Sounds like mismatch between the version of Libtool macro used to do the checks during configure, and the ltmain.sh file used to build libtool.
I would simply update libtool to the lastest version and run libtoolize -f by hand to ensure everything is up-to-date.
