user_vfp is not declared anymore in sys/user.h, but in specific internal kernel asm user.h in GLIBC. So building crashpad on ARMEL with such a GLIBC will fail to build. Also, sys/ptrace.h will not include the declarations for PTRACE_GET_THREAD_AREA and PTRACE_GETVFPREG in arm (they are in asm/ptrace.h and not included from sys/ptrace.h). So provide compatibility declarations accordingly for arm architecture.
