Indeed, the package is broken.  The commit
988ac06ce8cf9b1760094e0e2ff23960355d07eb introduces the fix:

       ;; Fix test_signals.vim. https://github.com/vim/vim/issues/7402
       #:make-flags (list "CFLAGS=-D_REENTRANT")

which breaks “#:make-flags '("LDFLAGS=-lexpat")” in vim-full.  More
specifically, the package vim-full contains duplicate #:make-flags in
its argument.  For instance,

Attached a fix.  Well, at least the package vim-full now builds.  Since
I am not a Vim user, could you confirm that with patch, the vim-full
package is functional?  If yes, I will submit the patch to guix-patches.

However, I am not sure to understand how all the machinery works.  For
instance, I do not understand why:

           ((#:make-flags flags)
            `("LDFLAGS=-lexpat"))

raises the backtrace:
