i see changes such as:

-       echo "${srcdir}/configure" | sed 's,icu/dummy/,icu/icu-xetex/,' >$@
+       d=$(srcdir); test "x$$d" = x. && d=../../icu/dummy; \
+       echo "$$d/configure" | sed 's,icu/dummy/,icu/icu-xetex/,' >$@

but it seems better to use $(abs_srcdir) in such cases? it is being set
in Makefile.

Best,
v.
