Subject: ext-toolchain-wrapper: force hash-style to 'both'
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9d5e6fa2fd4e48bdc0235f6bb902329b804b312d;p=buildroot.git

ext-toolchain-wrapper: force hash-style to 'both'

If ext-toolchain-wrapper was built with a gcc that uses hash-style 'gnu' by
default, the resulting binary might be unusable on other systems. The error
in this case is "Floating point exception".
Using hash-style 'both' solves this issue.
