Factorize target program transformations in the GDB_AC_TRANSFORM macro.
This patch introduces a new M4 macro GDB_AC_TRANSFORM to avoid repeating
the common idiom which is the transformation of target program names,
i.e. from gdb to sparc64-linux-gnu-gdb. It also makes gdb/configure.ac
and gdb/testsuite/configure.ac to use the new macro.
gdb/ChangeLog:
