[Message part 1 (text/plain, inline)]

Hello!

I'm building Sqlite 3.7.7.1 with libtool 2.4. I'm doing the cross
compile. Configuring sqlite with CC="my compiler". In compilation mode
everything is ok, but when I link, libtool tries to call the native
gcc (in spite of the fact, that CC="my compiler", not native).

The solution is to configure libtool by setting CC="my compiler". But
it's not good. I'm not good in m4 scripting, but in attached file is
that, what I changed in configure of libtool. In the old version of
libtool(2.2.6) everything is good. I'm using new libtool, because it
supports LTO.
