Is that a configure script generated by autoconf ?
Note that according to :
http://www.gnu.org/prep/standards/html_node/Configuration.html
It is recommended to pass the TARGET_CONFIGURE_OPTS as argument and not
inside the environment:
«
Specifying variables as arguments to configure, like this:
./configure CC=gcc
is preferable to setting them in environment variables:
CC=gcc ./configure
as it helps to recreate the same configuration later with
‘config.status’. However, both methods should be supported.
