build.sh tar M/C for xcb, mesa, xkeyboard
build.sh tar M/C for xcb, mesa, xkeyboard

Use same xcb module subdirs as git.
Mesa and xkeyboard-config tarballs were not being found.
MesaLib unpacks to Mesa, so sed is required to adjust its SRCDIR.
These tarballs work alternatively in topdir.
Note: The absence of autogen.sh triggers checkfortars() function.
