We read it later in grow_init_buf(). If CCS is the first thing received in
a flight, then it will use the init_msg from the last flight we received. If
the init_buf has been grown in the meantime then it will point to some
arbitrary other memory location. This is likely to result in grow_init_buf()
attempting to grow to some excessively large amount which is likely to
fail. In practice this should never happen because the only time we receive
a CCS as the first thing in a flight is in an abbreviated handshake. None
of the preceding messages from the server flight would be large enough to
trigger this.

Since the local symbol table is looked up before the global symbol
table, 'arch' assigned in the local symbol table of the DCL where MMS
is called would be seen before the 'arch' defined in descrip.mms.
Assigning it to the local symbol table in descrip.mms removes that
issue.

The sources for internal tests were sometimes badly formed, assuming
perl variables such as $target{cpuid_asm_src} contains only one file
name.  This change correctly massages all file names in such a

The test fixtures are (meant to be) useful for sharing common
setup. Don't bother when we don't have any setup/teardown.

This only addresses simple tests. Parameterized tests (ADD_ALL_TESTS)
will be made more user-friendly in a follow-up.
