[uml-devel] Fixing the __gcov_init problem

[Jeff Dike <jdike@addtoit.com>]

OK, below is my latest attempt at getting this right.  It provides a weak
definition of __gcov_init for gcc's that don't generate it, while gcc's that
do will have their's override this one.

The patch is against -bk8.

				Jeff

# Try to finally fix the __gcov_init thing corectly.
# This patch makes a weak definition of __gcov_init, which will be used if
# there is no other definition, and which will be overridden if there is a
# real definition.  Thus, if it is not used, then the weak definition will
# satisfy the EXPORT_SYMBOL, and if it is, then the real one will.
