fixes for arm-linux jit engine
It compiles without warnings using gcc 3.2.2, but crashes
at runtime, hope to fix it, though.

+ * libraries/clib/math/BigInteger.c
+ [!HAVE_GMP_H] (Java_java_math_BigInteger_assignString0): changed
+ return type to jint to match prototype of assignString0 when gmp
+ is used
+
+ * config/arm/common.h (sysdepCallMethod): changed into an inline
+ method, don't treat 'L' return type specially
+
+ * config/arm/jit.h (exceptionFrame): changed type of fields to
+ uintp to fix compilation warnings
+ (NEXTFRAME, PCFRAME, FPFRAME): remove now unnecessary casts
+
+ * config/arm/linux/jit-md.h (FIRSTFRAME): redefined using gcc's
+ __builtin_frame_address extension
+ (ARM_LINUX_HACK): removed since it's no longer necessary
+
+ * config/arm/linux/md.h (SP_OFFSET, FP_OFFSET): corrected to
+ match what current glibc does
+ (ARM_LINUX_HACK): removed since it's no longer necessary
