Ah, I see what you mean. Does the attached patch work for you?
If you have other build problems then
autoreconf && ./configure && cat base.buildinfo
in libraries/base should be enough to see if it works.

In rules/build-package-data.mk there are two lines:
$1_$2_CONFIGURE_OPTS += --configure-option=CFLAGS="$$(filter-out -Werror,$$(SRC_CC_OPTS)) $$($1_CC_OPTS) $$($1_$2_CC_OPTS)"
$1_$2_CONFIGURE_OPTS += --configure-option=LDFLAGS="$$(SRC_LD_OPTS) $$($1_LD_OPTS) $$($1_$2_LD_OPTS)"
If you add two more lines:
$1_$2_CONFIGURE_OPTS += --gcc-options="$$(filter-out -Werror,$$(SRC_CC_OPTS)) $$($1_CC_OPTS) $$($1_$2_CC_OPTS)"
$1_$2_CONFIGURE_OPTS += --ld-options="$$(SRC_LD_OPTS) $$($1_LD_OPTS) $$($1_$2_LD_OPTS)"
then does that fix the problem?
