I still don't get it why in distro/include/tclibc-uclibc.inc we have

PREFERRED_PROVIDER_virtual/libc = "uclibc"
PREFERRED_PROVIDER_virtual/libiconv ?= "libiconv"
PREFERRED_PROVIDER_virtual/libintl ?= "gettext"
PREFERRED_PROVIDER_virtual/nativesdk-libintl ?= "nativesdk-eglibc"
PREFERRED_PROVIDER_virtual/nativesdk-libiconv ?= "nativesdk-eglibc"

and in distro/include/tclibc-eglibc.inc, we have:

PREFERRED_PROVIDER_virtual/libiconv ?= "eglibc"
PREFERRED_PROVIDER_virtual/nativesdk-libiconv ?= "nativesdk-eglibc"
PREFERRED_PROVIDER_virtual/nativesdk-libintl ?= "nativesdk-eglibc"
PREFERRED_PROVIDER_virtual/libintl ?= "eglibc"
PREFERRED_PROVIDER_virtual/libc ?= "eglibc"
PREFERRED_PROVIDER_virtual/nativesdk-libc ?= "nativesdk-eglibc"
PREFERRED_PROVIDER_virtual/libc-locale ?= "eglibc-locale"

Is a specific reason why in the first case we use "=" and not "?="
like used everywhere else? This file is loaded last, so we have no
chance to override the value. regardless of the actual reason, don't
we need the change anyways?
