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.
