Hi all,
I just subscribed to this mail list and new in OpenWrt.
I looked but did not found anything about that problem:
When I try to build toolchain with multi-target, I got errors about
parameters which are included by config.cache are different due to
modifying with new parameters (output is below). There is a command (rm
-f config.cache;) in makefiles to remove config.cache but it is not
enough, if there is another config.cache file in subfolders (for example
gcc directory has several config.cache file). So I change this command
like that : "find . -name config.cache | xargs rm -rf ;". And It works
fine.
make[4]: Entering directory

configure: error: run `make distclean' and/or `rm ../config.cache' and

make[4]: *** [configure-build-libiberty] Error 1
(There are same command in other directories (glibc, eglibc and some
apps). If this patch is granted I will send patch for them too).
