[committed] Fix some compile warnings

[Ulrich Weigand]

Hello,

this fixes up a couple of (otherwise harmless) compiler warnings
in libgcc code.  Thanks to Andreas Jaeger for noticing these.

Bootstrapped/regtested on s390-ibm-linux and s390x-ibm-linux,
applied to mainline as obvious.

Bye,
Ulrich


ChangeLog:

	* unwind-dw2-fde.c (get_cie_encoding): Cast argument to strlen
	to eliminate warning.
	(linear_search_fdes): Declare p as unsigned.
	(binary_search_mixed_encoding_fdes): Likewise.
	* unwind-dw2.c (get_cie_encoding): Cast argument to strlen
	to eliminate warning.
	* config/s390/linux.h (MD_FALLBACK_FRAME_STATE_FOR): Add missing
	type cast.
