The library has a number of special-purpose configuration parameters
which you can find in @file{Makeconfig}. These can be overwritten with
the file @file{configparms}. To change them, create a
@file{configparms} in your build directory and add values as appropriate
for your system. The file is included and parsed by @code{make} and has
to follow the conventions for makefiles.
It is easy to configure the GNU C library for cross-compilation by
setting a few variables in @file{configparms}. Set @code{CC} to the
cross-compiler for the target you configured the library for; it is
important to use this same @code{CC} value when running
@code{configure}, like this: @samp{CC=@var{target}-gcc configure
@var{target}}. Set @code{BUILD_CC} to the compiler to use for for
programs run on the build system as part of compiling the library. You
may need to set @code{AR} and @code{RANLIB} to cross-compiling versions
of @code{ar} and @code{ranlib} if the native tools are not configured to
work with object files for the target you configured for.
