  [Changes from V1:
- Use always_inline only in BPF target.]

The function __hardcfr_check_fail in hardcfr.c is internal and static
inline.  It receives many arguments, which require more than five
registers to be passed in bpf-none-unknown targets.  BPF is limited to
that number of registers to pass arguments, and therefore libgcc fails
to build in that target.  This patch marks the function with the
always_inline attribute, fixing the bpf build.

Tested in bpf-unknown-none target and x86_64-linux-gnu host.

libgcc/ChangeLog:

	* hardcfr.c (__hardcfr_check_fail): Mark as always_inline.
