I forgot to add: I noticed this particular issue while trying to build
libogg 1.3 in parallel mode.

Turns out the install_sh -d stuff is NOT safe in parallel mode, it errors out
while trying to create a directory that already exists. Thus, I have even
*more* trouble understanding the restriction against mkdir -p considering
install_sh does not even do what the mkdir -p restriction is supposed to 
avoid in the first place...
