[patch] Enable long section names for --add-gnu-debuglink

[marco atzeri <marco dot atzeri at gmail dot com>]

Attached patch to enable usage of long section names
when

--add-gnu-debuglink=<file>
     Add section .gnu_debuglink linking to <file>

is requested.

Otherwise on cygwin some time the section name is cut from
".gnu_debuglink" to ".gnu_deb"


$ objdump -h /usr/bin/cygcrypto-1.0.0.dll
