Thanks for that, very helpful. I've just uploaded a new package that 
fixes this bug in the manner you suggested.

Bug#805941: libpcre2-dev: arch-dependent file in "Multi-Arch: same" package

[Jakub Wilk]

Package: libpcre2-dev
Version: 10.20-1
Severity: important
User: multiarch-de...@lists.alioth.debian.org
Usertags: multiarch

libpcre2-dev is marked as "Multi-Arch: same", but the following file is 
architecture-dependent:


/usr/bin/pcre2-config

An example diff between i386 and amd64 is attached.

Thanks for the bug report. I think this means libpcre2-dev should be
marked as Multi-Arch: no?

That's the lazy^Weasy way, yes.

The hard way is to make the script identical across all architectures. 
Then the package could remain "Multi-Arch: same".


So let's look what the architecture-dependent bits are:


case `uname -s` in
 *SunOS*)
 libR=" -R${prefix}/lib/i386-linux-gnu"
 ;;
 *BSD*)
 libR=" -Wl,-R${prefix}/lib/i386-linux-gnu"
 ;;
esac


This is no-op on Linux, and adds harmful rpath on kFreeBSD.
This part can (and should!) be removed.


if test ${prefix}/lib/i386-linux-gnu != /usr/lib ; then
 libS=-L${prefix}/lib/i386-linux-gnu
fi


/usr/lib/i386-linux-gnu is already within linker's search path.
So this part can be safely removed, too.

So it looks like the hard way is not that hard after all. :-)
