From: Hauke Mehrtens Date: Sat, 31 Mar 2018 19:28:32 +0000 (+0200) Subject: build: Improve GCC version detection X-Git-Tag: v18.06.0-rc1~498 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=d6d3db05436952f68f47d35df58ad5050b1f2d66;p=oweals%2Fopenwrt.git build: Improve GCC version detection This now makes sure that the beginning of the version number gets checked and "4.4.5" will not match was a supported version. GCC 8 and GCC 9 are now marked as supported, but we probably have to fix some problems for them.
