misc/check-installed-headers-c failing due to upstream kernel change

[Vineet Gupta]

Hi,

It seems a recent upstream kernel change (went in 5.0-rcX) 81c9d43f9487
("kernel/sysctl: add panic_print into sysctl") trips one of the glibc tests.

	FAIL: misc/check-installed-headers-c

| :: sys/sysctl.h
| ::::
| *** Obsolete types detected:
| ~/install/compilers/arc-linux-gnu/sysroot/usr/include/linux /sysctl.h:
| KERN_PANIC_PRINT=78, /* ulong: bitmask to print system info on panic */

It doesn't seem to like ulong (inside a comment). I don't have enough foo to fix
it, but wanted to bring it to notice anyways.

Thx,
