+Upstream-Status: Inappropriate [The fix is already in upstream cvs repo, but not in the stable release]
+
+When working on the self-hosted-image work, I found in the target
+"bitbake eglibc-initial -c install" always failed:
+
+make[1]: Entering directory `/raid/pe2/build/tmp/work/i586-poky-linux/eglibc-initial-2.13-r18+svnr14157/eglibc-2_13/libc'

+make: *** [install-headers] Error 2
+ERROR: oe_runmake faile
+

+reset at some place.
+
+Further investigation shows this is a bug of make-3.82:
