[pkgsrc] ICU needs configure CFLAGS='-03'

[tlaronde%polynum.com@localhost]

Hello,

As a dependency to firefox, ICU needs to be recompiled.

I'm on:

NetBSD 6.1.5_PATCH amd64

This is pkgsrc-2017Q3.

The ICU fails during configure with "C compiler cannot create
executables". I've found on the net that invoking configure with:

./configure CFLAGS='-03'

does the trick.

But I don't understand how autoconf and al. work and I don't
understand either how the pkgsrc framework invokes configure.

Trying to set whether CONFIGURE_ARGS or adding to CFLAGS doesn't do it.

Does anybody know how to instruct "pkgsrc" to set this or,
alternatively, what is the name of the sentry file to put in the
work directory after invoking configure by end so that pkgsrc will
proceed?

TIA for any tip.

Best,
