[PATCH] gcc_update explicit use of "svn"

[David Edelsohn]

contrib/gcc_update currently uses "svn" explicitly to determine the
Revision and Branch instead of the $GCC_SVN shell variable used in
other instances in the script. This patch uses the shell variable in
all instances.

Thanks, David

        * gcc_update: Use $GCC_SVN to retrieve branch and revision.
