    gdb: Remove unused signal mask
    
    In the following commit:
    
        commit 7feb7d068ae65557ede03c36468ebac61b0939ca
        Date:   Mon May 11 12:08:03 2009 +0000
    
    The last useful uses of normal_mask in linux-nat.c were removed, since
    then this variable has sat around being initialised, but never used.
    There should be no user visible changes after this commit.
    
    gdb/ChangeLog:
    
    	* linux-nat.c (normal_mask): Delete.
    	(_initialize_linux_nat): Don't initialise normal_mask.
