Jake Burkholder 02318dac2c Remove the leading underscore from all symbols defined in x86 asm
and used in C or vice versa.  The elf compiler uses the same names
for both.  Remove asnames.h with great prejudice; it has served its
purpose.

Note that this does not affect the ability to generate an aout kernel
due to gcc's -mno-underscores option.
