Cross compile not working

[Flinkbaum]

What is the problem

Trying to compile the rpcsvc-proto with a different --build and --host option results in error

../rpcgen/rpcgen: 1: Syntax error: word unexpected (expecting ")")

Steps to reproduce

autopoint --force
aclocal -I m4
autoconf --force
autoheader
automake --add-missing --copy --foreign --force-missing
./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=aarch64-unknown-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-dependency-tracking --disable-silent-rules --docdir=/usr/share/doc/rpcsvc-proto-1.4.3 --htmldir=/usr/share/doc/rpcsvc-proto-1.4.3/html
make -j16

What is the issue

../rpcgen/rpcgen is compiled for aarch64 so executing it does not work.

Suggestion

I'd suggest adding an option (e.g. --cross-execute) so that the user can specify a command with which rpcgen will be executed (like qemu-aarch64 -L '<aarch64-chroot>').
If rpcgen is only used in an intermediate step, then it may be possible to compile it for the build-architecture.
