This is how it currently gets compiled:

    $ rm git-sh-i18n--envsubst sh-i18n--envsubst.o; make -j 5 all V=1
    gcc -o sh-i18n--envsubst.o -c   -g -O2 -Wall -I.  -DHAVE_PATHS_H
-DSHA1_HEADER='<openssl/sha.h>'  -DNO_STRLCPY -DNO_MKSTEMPS
sh-i18n--envsubst.c
    gcc  -g -O2 -Wall -I.  -DHAVE_PATHS_H
-DSHA1_HEADER='<openssl/sha.h>'  -DNO_STRLCPY -DNO_MKSTEMPS -o
git-sh-i18n--envsubst   sh-i18n--envsubst.o libgit.a xdiff/lib.a  -lz
-lcrypto -lpthread

I tried to remove some of those library includes. But it'll
complain. However if I do:

    diff --git a/sh-i18n--envsubst.c b/sh-i18n--envsubst.c
    index 8db71b1..7d4c870 100644

It'll compile stand-alone with no library includes at all. Maybe I
should just modify it to have basic versions of those two x* functions
so we can compile it completely stand-alone.
