I do not know how other distributions do that. Debian 'gdb' does not seem to
ship jit-reader.h at all if I read Debian package listing correctly.

For other libraries Debian ships the file like Fedora does:

https://packages.debian.org/sid/amd64/libgpm-dev/filelist
	/usr/include/gpm.h
	/usr/lib/x86_64-linux-gnu/libgpm.so
https://packages.debian.org/sid/i386/libgpm-dev/filelist
	/usr/include/gpm.h
	/usr/lib/i386-linux-gnu/libgpm.so

What would happen if /usr/include/gpm.h content differs between amd64 and i386
build?  Fedora would refuse to install the second package due to conflicting
file content (sure unless forced to do so).

As I said this patch may not affect much/any other distros because
 * at least Debian does not ship jit-reader.h at all
 * other distros may not consider GDB as a multilib package
