Subject: boost: use backtick instead of $(shell ...) make function
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e77354d28f8087fed75b2fe66fbd50799e68eca7;p=buildroot.git

boost: use backtick instead of $(shell ...) make function

Also remove the variables TARGET_CC_VERSION and HOST_CC_VERSION which
lack the BOOST_ prefix and are used only once.
