It seems that this will have to change after all. At least in version
2.20.51.0.2, gas does not except mfcr with two operands (giving one of its
"Error: junk at end of line" diagnostics), but does accept mfocrf.

Also, according to:
http://opensource.apple.com/source/cctools/cctools-590.18/RelNotes/Private_CompilerTools.html

[begin quote]
Changes since the last release (cctools-579 for
the 5.18 Mac OS X Xcode 2.1 Developer release):
...
Changed the PowerPC assembler to accept "mtocrf" as a synonym
   for "mtcrf" and accept "mfocrf" as a synonym for "mfcr". And when
   these mnemonic is used the argument must have exactly one bit set.
   Also changed otool(1)'s disassembler to use mtocrf/mfocrf when bit
   11 is set. Radar bug #4034280.
[end quote]

So, unless I'm misinterpreting things, as of cctools-580 for the 5.18 Mac OS X
Xcode 2.1 mfocrf is supported on Darwin as well.
