[PATCH] libgcov and umask

[Johan Kristell]

Profiling an application with a to restrictive set umask currently fails
due to libgcov inheriting the umask of the application.

This patch fixes this by temporarily changing the umask when writing to
the data file.

Tested on i386-linux

	* libgcov.c (gcov_exit): Temporarily change the umask to allow
	writing to the data file from the library even if the umask of
	the application is set to restrictive.

	* gcc.misc-tests/gcov-12.c: New testcase.
