Thank you larsi! the patch works and the initial compilation is
fine. The build log is attached below. Although now i'm getting a new
error such as:

LC_ALL=C ./temacs -batch  -l loadup --temacs=pdump
Loading loadup.el (source)...
dump mode: pdump
...
Loading files.el (source)...
(require pcase) while preparing to dump
make[1]: *** [Makefile:584: emacs.pdmp] Error 255

Thanks!
