The reason for it was that Anders Johansson got this after my previous
commit 3c1d3a7 (I think he used 7.4 but I'm not entirely sure):
/bin/sh: command substitution: line 0: syntax error near unexpected token `('
/bin/sh: command substitution: line 0: `uname -s -r -m|sed \"s/ /-/g\"|tr
\"[A-Z]\" \"[a-z]\"|tr \"/()\" \"___\"'
My patch was sloppy since I didn't really figure out exactly why that
happened, but removing the escapes worked for him, and for myself it
works either way (which is odd in itself).
You're right $(BUILDDIR) always is used inside ", so they ought to be
escaped there. I can't find any difference in this regard between 7.4,
7.6, 7.8 and 7.9 either. I guess I need to look into Anders problem
more closely.
