From: Samuel Martin Date: Sun, 3 Jul 2016 13:47:37 +0000 (+0200) Subject: toolchain/toolchain-common.in: add BR2_TOOLCHAIN_HAS_LIBQUADMATH hidden symbol X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b16f8c7876482864b391963588362e5bdbd99d01;p=buildroot.git toolchain/toolchain-common.in: add BR2_TOOLCHAIN_HAS_LIBQUADMATH hidden symbol This hidden symbol allow to know when libquadmath can be built and installed. Also, declaring this symbol in toolchain-common.in allows to use it in both external and buildroot toolchain backend. This will be needed for adding/improving the fortran support.
