more compiling and z/OS

The only other failing test in the z/OS smokes is also 
compiling-related.  It is possible to embed Perl in a C language 
application, using ExtUtils::Embed.  The test file for that, Embed.t, is 
failing.  I have instrumented Embed.t to give debugging output.  The 
output is given below.  Embed.t is attached to this email

What is happening is that it is trying to compile a .c file that is in 
the __DATA__ at the end of Embed.t (hence you can see it in the 
attachment) into the file 'embed_test'.  It's not finding several Perl 
subroutines, and the loader exits 8.  Nevertheless, Embed.t calls 
system('./embed_test') and that results in some garbage output.  The 
MALFORMED lines are from my program that I used to translate from 
UTF-EBCDIC back to ASCII so I can read it.  The garbage output is not 
UTF-EBCDIC, the malformation lines tell what the code points are.  My 
guess is that it is binary.

I don't know enough about the z/OS compile-load system to debug this, 
but hopefully the problem is obvious to someone who does.

Tracing output follows:
