a2bc88bdb6 fixes, improvements, __interrupt 
Fixes/workarounds:
- octal escape sequence is to be terminated no later than after three
octal digits:
"\1011" is now parsed equivalently to "A1"
- workaround truncation of immediate operands to 16 bits in MIPS
instructions addi[u], subi[u], slti[u], andi, ori, xori in RetroBSD's as
(disabled since as is being fixed).

Improvements:
- warn on string literal truncation when initializing array of char
- generate trap/break-less form of MIPS div[u]

New:
- experimental support for __interrupt functions (x86/huge only)

51a8fd3313 Assembler: added support for large constants for 2-reg variants (macros) 
of 3-reg instructions (add, addu, and, or, slt, sltu, sub, subu, xor).
When mode ".set at" enabled, an additional LI instruction is inserted
sing $1 as a scratch register.

f105cb5bbd /bin/cc command modified to use SmallerC compiler by default (not LCC). 
For LCC, please use /bin/lcc instead.

I believe SmallerC is mature enough to try to use it as a primary compiler.
System include files might need some changes (ifdefs) to adapt.

07b6681eef Improve configsys option parsing 
Up until now all the options in the config system have only been
able to take one word (or one string with no spaces) as a parameter.
This update improves it so it takes everything after the = up until
the end of the line (or the first #) as the parameter.

ce1f5ce4dc Improved congigsys option parser 
Up until now, options have only been able to have one single word
(or string with no spaces) as their value.  This small patch improves
that and includes everything to either the end-of-line or # (for in-line
comments) as the parameter for the option.
