Cross-compiling for ARM is notoriously difficult but the following
usually works:
$ ./configure --dest-cpu=arm --without-snapshot
$ make \
CC=/path/to/arm-gcc \
CXX=/path/to/arm-g++ \
CFLAGS+=-march=armv5t \
CXXFLAGS+=-march=armv5t \
LDFLAGS+=
I've left LDFLAGS empty here but you can use it to pass additional
linker switches.
