This shoul be ,(string-append "CC=" (cc-for-target)), such that the 
cross-compiler
is used when cross-compililng.

Why are you adding "-g -O2" to LDFLAGS? I understand adding it to CFLAGS,
but I don't see why it would be added to CFLAGS.

This needs to be (search-input-file "bin/gzip") instead of (which "gzip")
for cross-compilation purposes ('which' searches for a native "gzip" in $PATH)
'search-input-file' is not yet defined on 'master' (it's only on 'core-updates'
currently), so you could do something like

  (string-append (assoc-ref inputs "gzip") "/bin/gzip")

Ditto (and you need to add "bash-minimal" to "inputs").

Ditto.

If you fix 'sendemail' to install things in "sbin" instead of
"usr/sbin", then you can do (search-input-file inputs "bin/sendmail").
