There's some info in the wiki on it, but basically the steps are:
1. change the configure script (see attached patch for 3.2.6)
2. configure with something like this (in my case an arm sa1110):
cd $PATH/sqlite-3.2.6
CC=arm-sa1100-linux-gnu-gcc CXX=arm-sa1100-linux-gnu-g++ \
CFLAGS=-I$TOOLCHAIN_BASE/include BUILD_CC=gcc \
./configure --host=i686-pc-linux --target=arm-sa1100-linux \
--disable-shared --disable-tcl --prefix=$PATH_INSTALL
3. change the Makefile a bit, setting 'BCC' to your regular compiler and (if
you want) add the static build flag, for example doing something like this:
mv Makefile Makefile.sed
cat Makefile.sed | sed 's/^BCC.*/BCC = gcc/' | sed 's/^LTLINK.*/&
-all-static/' > Makefile
rm Makefile.sed
4. make && make install
Mind you, depending on which core you have and whether you want floating
point, you might find the other patch attached usefull as well. It is from an
earlier posting of myself:
"In order to wrap this up: apparently there's a feature / bug (choose one) in
any ARM core earlier than v5 due to which a float will be stored in big
endian quad order. The processor in this particular case is an SA1110, which
is default little endian while having a v4 core. (and thus is 'swapping'
the quads)."

Best,
