Romain, All,

On 2016-12-04 21:58 +0100, Romain Naour spake thusly:

I'm not against having variables named the same across packages, but
here I think $(2)_BUILD_OPTS would be more appropriate.

Usually, those options entirely override the default ones. For example,
if you provide FOO_INSTALL_STAGING_OPTS for an autotools package, then
the default (just 'install') is lost:

    package/pkg-autotools.mk:
    159 $(2)_INSTALL_STAGING_OPTS»  ?= DESTDIR=$$(STAGING_DIR) install

OTOH, I find this to be counter-intuitive for a user, and I would prefer
the options to add rather than replace.

But consistency trumps it all, so we should do the same for waf
packages:

    $(2)_INSTALL_STAGING_OPTS ?= install --destdir=$$(STAGING_DIR)

Ditto.
