o .align cannot handle fill-data-width larger than 0xFF/8-bits. It
should be possible to define a 32-bits pattern.

- intended used in .text sections. If you require something else,
- use .align <size>,0x00)

o .align: Implement a 'bu' insn if the number of nop's exceeds 4
within the align frag. if(fragsize>4words) insert bu fragend+1
first.
o Evaluation of constant floating point expressions (expr.c needs
work!)
