icu-config lies about include dir

[Tobias Leich]

The include dir is no longer PREFIX/include, but rather PREFIX/include/x86_64-linux-gnu.

This breaks building parrot, nqp and rakudo (Perl6) from source. And I guess other source builds which rely on libicu are also affected.

A patch how icu-config should look like is attached, but I dunno if this is a generated file.

The attachment "icu-config.patch" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

Please stop using icu-config, instead use provided pkg-config files.

Icu has transitioned to be multiarch, and thus one can have i686, amd64, armhf etc libicu-dev's co-installed and icu-config is not flexible enough to tell one which one should be used.

pkg-config on the other hand can resolve it.

Furthermore, one doesn't need to add /usr/include/$(tripplet) cflags / search directories as they are default in the compiler.

icu-config cannot encode any single architecture.

[Dimitri John Ledkov (xnox)]

Please help affected projects to check pkg-config first for icu, and only if not available fall back to icu-config.
