[Bug-dejagnu] [patch] allow testing of glibc code

[Will Cohen]

When linking with recent versions of glibc, 2.2.4, alternative functions
are suggested like below:

xxx.o: In function `writef':
xxx.o(.text+0x1f): the use of `tmpnam' is dangerous, better use
`mkstemp'

The attached patch allow dejagnu to ignore these warning and give more
accurate test result. Without this patch many of the tests will fail.
Could we get this patch put into dejagnu? The changelog entry is below.

        * lib/target.exp: Ignore ld's warning about alternative functions
        to use.
