sys-libs/glibc: add USE=multiarch (enabled by default) Normally multiarch should be enabled (where available). But sometimes disabling multiarch is useful: - to workaround or validate bugs specific to selected runtime arch or IFUNC handling. - to get code that matches -march= CFLAGS setting Bug: https://bugs.gentoo.org/659030 Package-Manager: Portage-2.3.40, Repoman-2.3.9 sys-libs/glibc/glibc-2.27-r5.ebuild | 4 +++- sys-libs/glibc/glibc-9999.ebuild | 4 +++- sys-libs/glibc/metadata.xml | 1 + 3 files changed, 7 insertions(+), 2 deletions(-) diff --git a/sys-libs/glibc/glibc-2.27-r5.ebuild b/sys-libs/glibc/glibc-2.27-r5.ebuild index 0e9283a66ca..e123d28e80d 100644 --- a/sys-libs/glibc/glibc-2.27-r5.ebuild +++ b/sys-libs/glibc/glibc-2.27-r5.ebuild @@ -32,7 +32,7 @@ PATCH_VER=2 SRC_URI+=" https://dev.gentoo.org/~dilfridge/distfiles/${P}-patches-${PATCH_VER}.tar.bz2" SRC_URI+=" multilib?
