Fix for unlikely text section grouping in conjunction with gcc's -ffunction-sections

[Jeff Law]

Normally when GCC wants to emit an unlikely to be executed function, 
it'll put it in the .text.unlikely section.


However, when -ffunction-sections is enabled, the function will be 
placed into the .text.unlikely.<funcname> section.  Thus 
.text.unlikely.* sections need to be handled in the ELF linker script.

At some point in the past, GCC used something like .text.name_unlikely, 
which was a horrible choice.  I chose to keep that old style since we 
might be linking older objects with the older style name.

Note I didn't want to use .text.unlikely* as that would unfortunately 
match a function named "unlikely" when -ffunction-sections is active.

OK to install?
