you are passing the compiler as the target-architecture.
not going to work.

so you passed "arm-linux" as the target-arch and configure looks for a
compiler named "arm-linux-gcc".
you know that your compiler is arm-linux-gnueabi-gcc. does that ring a bell?

./configure --host=arm-linux-gnueabi


also, rather than exporting envvars (CC, CFLAGS), you should probably
pass them as flags to configure:

./configure --host=arm-linux-gnueabi CFLAGS="-march=armv7+simd"

(no need to set CC, as configure does that for you via the "--host"
flag. passing CFLAGS as argument will make it local to the build-toolchain)

PS: all of the above is not specific to Pd, but applies to virtually all
autotools projects; remember it if you intend to cross-compile other stuff.
