Subject: hurd: Add OPTION_GLIBC_P and OPTION_GLIBC
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a3b203b67c5ab5cd48d19d8aeea46b564db49a30;p=thirdparty%2Fgcc.git

hurd: Add OPTION_GLIBC_P and OPTION_GLIBC

GNU/Hurd uses glibc just like GNU/Linux.

This is needed for gcc to notice that glibc supports split stack in
finish_options.

	PR go/104290
gcc/ChangeLog:
	* config/gnu.h (OPTION_GLIBC_P, OPTION_GLIBC): Define.

(cherry picked from commit 29eacf043b6e8560c5c42d67f7f9b11e4e2cb156)
