Subject: toolchain/gcc: switch to version 8 by default
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d509463816bf593de841398914f0d9d68bf76458;p=openwrt%2Fstaging%2Fadrian.git

toolchain/gcc: switch to version 8 by default

Main motivation for this commit is the introduction of
`-ffile-prefix-map=` which alows reproducible build path.

Compile tested on Linux and macOS without errors on the following
targets:

 * ath79
 * imx6
 * brcm2708
 * brcm63xx
 * ixp4xx
 * ramips
 * sunxi
 * x86

Thanks to Andre for the iremap fixup.
