Description
server build now breaks in Centos 7/el7. client-only build still works OK.
example errors:
CC [M] /home/bogl/lustre-release/lustre/mdd/mdd_dir.o
/home/bogl/lustre-release/lustre/mdd/mdd_dir.c: In function ‘mdd_migrate_create’:
/home/bogl/lustre-release/lustre/mdd/mdd_dir.c:3396:26: error: argument to ‘sizeof’ in ‘memset’ call is the same expression as the destination; did you mean to dereference it? [-Werror=sizeof-pointer-memaccess]
memset(mgr_ea, 0, sizeof(mgr_ea));

I believe this is due to the recent landing in master of commit de2d5808bd2987f76d2486272e1a9c192ba277d4; LU-5223 lmv: build master LMV EA dynamically build via readdir
It appears the gcc v4.8.2 in el7 is a bit pickier about some things than earlier gcc versions.
