Same here.  I don't think that this variable is meant to be changed
by testcases when you just want to change it for a few tests.
Otherwise, you run the risk of affecting all the other testcases,
which set the timeout to $gdb_test_timeout at the start of every
testcase (this was done to prevent a change of timeout duration
from affecting subsequent testcases). See gdb_init:

    # Reset the timeout value to the default.  This way, any testcase
    # that changes the timeout value without resetting it cannot affect
    # the timeout used in subsequent testcases.
    global gdb_test_timeout
    global timeout
    set timeout $gdb_test_timeout
