[PATCH] scripts: Translate profile2linkerlist.

[Jorge Natz <jorgenatzdev@gmail.com>]

profile2linkerlist.pl is a script that takes the sorted output of the 
readprofile command and turns it into a list of C functions in a 
format for linker lists. Make the script more portable across POSIX 
systems. This script does not use any shell-specific features, only 
POSIX ones. A POSIX shell is present on all UNIX systems, while Perl 
is not as commonplace.
