Try setting SHELL in the environment while quoting the file name:

  set SHELL="C:\Program Files\Git\usr\bin\sh.exe"

and then run Make again.  You may need to use "make -e" to have the
environment override the setting inside the Makefile.

Alternatively, you could copy 'C:\Program Files\Git\usr\bin\sh.exe' to
a directory without whitespace and put that directory ahead of
'C:\Program Files\Git\usr\bin' on PATH.  Just sh.exe, nothing else.

As yet another alternative, you could create a directory symlink to
'C:\Program Files\Git\usr\bin' (using the mklink command) and put that
symlink on your PATH ahead of 'C:\Program Files\Git\usr\bin'.

In general, I don't recommend using the native Windows port of Make
for building packages whose Makefiles assume a Posixy shell.  Use MSYS
instead.  But maybe liblzma is simple enough that it will work for you
with some tweaking.
