# Build mingw with our freshly built cross compiler
# Since somewhere between llvm 3.8 and 3.9, SVN rev 273373, git mirror commit
# d319cd64a4a15,, llvm-ar tries to detect the format (gnu vs bsd) of the
# existing .a file. For files generated by genlib, it seems to detect the
# wrong format, leading to lld later segfaulting when trying to link.
# Force the flag -format gnu to llvm-ar in this step to work around this issue.
