Subject: configure: Add an armv7-win32-gcc target
X-Git-Tag: v1.8.0~779^2~2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b08a0b07d4debb232a2b6679c9fd2903dffb9ebe;p=libvpx

configure: Add an armv7-win32-gcc target

This builds for windows on arm, with llvm-mingw. The target triplet
is named -gcc since that's how similar existing targets are named,
even though it technically runs clang (via frontends named
"$CROSS-gcc").

Assemble using $CC -c since there's no standalone assembler
available (except perhaps llvm-mc).
