We received this report on automake from Kolanich (thanks): (https://debbugs.gnu.org/cgi/bugreport.cgi?bug=43945):
Hello. When I crosscompiled some app I had to patch some file generated by autoreconf -i, where I have to add thumbv7[arm] (using the analogy to armv7[arm] already present there) there. He later followed up with the necessary change, which turned out to be for config.sub: --- a/config.sub +++ b/config.sub .. - | arm | arm[bl]e | arme[lb] | armv[2-8] | armv[3-8][lb] | armv7[arm] \ + | arm | arm[bl]e | arme[lb] | armv[2-8] | armv[3-8][lb] | armv7[arm] | thumbv7[arm] \ Dmitry, or anyone, wdyt? I know little about the myriad arm architectures. --thanks, karl.
