Some key bits of the log:

So where does this come from? packagegroup-core-standalone-sdk-target.bb
leads us to LIBC_DEPENDENCIES which leads to:

$ cat conf/distro/include/tclibc-eglibc.inc

LIBC_DEPENDENCIES = "libsegfault \
		     eglibc \
		     eglibc-dbg \
		     eglibc-dev \
		     eglibc-utils \
		     eglibc-thread-db \
		     ${@get_libc_locales_dependencies(d)}"

LIBC_LOCALE_DEPENDENCIES = "\
	eglibc-localedata-i18n \
	eglibc-gconv-ibm850 \
	eglibc-gconv-cp1252 \
	eglibc-gconv-iso8859-1 \
	eglibc-gconv-iso8859-15"

so I suspect you either need to provide some of these things, or reset
those variables...

Cheers,
