           Summary: mkbundle failes for PPC64
    Classification: Mono
           Product: Mono: Tools
           Version: 2.4.x
          Platform: PowerPC-64
        OS/Version: openSUSE 10.3

mkbundle fails with a linker error for PPC64. 

The make check for mkbundle generates one of too failures depending on the
version of GCC used in the build:

Testing mkbundle...
temp.s: Assembler messages:
temp.s:3: Warning: alignment too large: 31 assumed


Testing mkbundle...
/usr/bin/ld: insuffcient memory

Reproducible: Always

Steps to Reproduce:
1. Configure mono for PPC64
2. make
3. make check
Actual Results:  
The make check fails at Testing mkbundle...

Expected Results:  
mkbundle should pass this simple test

The important clue is:

temp.s:3: Warning: alignment too large: 31 assumed

mkbundle generates temp.s which includes in the asm statement:

      .align 32

Which on PPC64 means 4GB alignment (generates 4 billion bytes of nops). I
assume the intent is 32 bytes and perhaps on other architectures that may be
the results, but for PPC64 this is a bad idea.

Net if "as" does not fail the next statement is a link (ln) that will fail by
running out memory or exceeding file limit.
