    pic32: Fix crt0.S build error
    
    xc32 compiler version 3.xx starts to complain
    about constant value range
    
    Error: repos/apache-mynewt-core/kernel/os/src/arch/pic32/startup/crt0.S: Assembler messages:
    repos/apache-mynewt-core/kernel/os/src/arch/pic32/startup/crt0.S:314: Error: operand 3 out of range `addiu $10,$0,0xFFFFFFFC'
    
    previous compiler did not complain
    
    This changes 32bit unsigned interpretation of -4 (0xFFFFFFFC)
    to just -4, so 2.5 and 3.x versions are happy.
    
    -4 can be found in SDK provided crt0.S files.
