>Description:
All tests in /usr/tests/usr.bin/make/t_make fail on powerpc/booke,
although they pass successfully for other powerpc sub-archs, i.e., oea and
ibm4xx. Log from atf-run(1) is like:

| tc-start: 1618319044.259295, archive
| tc-so:Executing command [ make -f /usr/tests/usr.bin/make/unit-tests/Makefile archive.out ]

| tc-se:-rm -f libprog.a
| ...(snip)...
| tc-se:-exit status 0
| tc-se:+Cannot map anonymous memoryCannot allocate memory: Cannot allocate memory
| tc-se:+exit status 1

The first error message seems to come from ld.elf_so:

| % find /usr/src -type f -printx | xargs grep "Cannot map anonymous memory"
| /usr/src/libexec/ld.elf_so/xmalloc.c:           xprintf("Cannot map anonymous memory");
| %

The failure occurs both for kernel and userland built with GCC 9 and 10.

make(1) itself works fine as far as I can see. At least, kernel can be
self-built on booke.

Note that these tests pass on mips64-eb, which shares uvm/pmap with booke.
>How-To-Repeat:
"cd /usr/tests/usr.bin/make && atf-run t_make" on powerpc/booke.
>Fix:
N/A

 Decrease MAXSSIZ from ~256MB to 32MB (same as oea).

 This fixes tests in /usr/tests/usr.bin/make, that run with "ulimit -v 200000",
 fail with "Cannot map anonymous memory".

 Although I'm not fully convinced whether this limit is reasonable or not,
 old MAXSSIZ of ~256MB is too much anyway.
