cross-compiling to mipsel

[Daniel Eiband]

I hope this mailing list is suitable, because it might be that my probem 
is due to a libtool bug.

I try to cross-compile libgcrypt for a mipsel host in a buildroot like 
environment. It works fine, except on machines with a host version of 
libgpg-error installed in /usr/lib/ (libgpg-error was configured with 
--prefix=/usr, but installed into the 
$(TARGET_TOOLCHAIN_STAGING_DIR)/usr/lib).

My configure looks like this:

PATH=$(TARGET_TOOLCHAIN_PATH) \
CFLAGS="$(TARGET_CFLAGS)" \
CPPFLAGS="-I$(TARGET_TOOLCHAIN_STAGING_DIR)/usr/include" \
LDFLAGS="-L$(TARGET_TOOLCHAIN_STAGING_DIR)/lib 
-L$(TARGET_TOOLCHAIN_STAGING_DIR)/usr/lib" \
./configure \
	--target=$(GNU_TARGET_NAME) \
	--host=$(GNU_TARGET_NAME) \
	--build=$(GNU_HOST_NAME) \
	--program-prefix="" \
	--program-suffix="" \
	--prefix=/usr \
	--sysconfdir=/etc \
	--disable-nls \
	--disable-largefile \
	--enable-shared \
	--enable-static \
	--disable-rpath \
	--disable-asm \
	--with-gpg-error-prefix="$(TARGET_TOOLCHAIN_STAGING_DIR)/usr"

If there is libgpg-error installed on the build machine, make stops 
while linking:

/usr/lib/libgpg-error.so: could not read symbols: File in wrong format

Of course /usr/lib/libgpg-error.so is in wrong format. Is there a way to 
tell libtool not to use host libraries when cross-compiling?

Is this a common libtool issue or a particular libgcrypt problem?
