From bf279849ad59538a1518c667c0795ec1fe9dbd66 Mon Sep 17 00:00:00 2001 From: Vincenzo Frascino Date: Fri, 30 Aug 2019 14:58:56 +0100 Subject: [PATCH] lib/vdso: Build 32 bit specific functions in the right context clock_gettime32 and clock_getres_time32 should be compiled only with a 32 bit vdso library. Exclude these symbols when BUILD_VDSO32 is not defined.
