OK, once more for the hard of thinking.  Sorry, I spoke too soon (again).
There *is* an inherent problem with running programs from shell calls.
There is no such thing as a subshell, merely calls to the one sleeping shell.

Executing *commands* in a shell call is no problem, but when you actually
cause a program to load and run, (such as compile or assemble would), then
the shell gets confused by having more than one program running from it.
E.g., I ran emacs, then from emacs I ran an assembly, successfully returning.
When I try to exit emacs, I usually get a crash or a system-hang.

It is still possible to have a program to create an exec file that does your
build for you, then a shell script that runs the make, then its output script
(exec) file...
