configure: error: C compiler cannot create executables

[RobertKoval]

Can't configure packages.

See `config.log' for more details.

p.s. config.log removed after error, because it's in /tmp, so I can't open it.

I think it's related to old gcc: gcc version 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) But I can't update gcc, because I get this error. Same error on other packages.

Gist for gcc: https://gist.github.com/RobertKoval/6045ef641a8bb13faa170c487beb8035

brew gist-logs is supposed to include config.log, but it doesn't in this case because it's in a subdirectory. =/ You can brew install -dv gcc@4.9 and then once it fails select shell, which will give you access to config.log. Or try…

brew install -s hello
brew gist-logs hello

I just reinstall linuxbrew with my previous fix: https://github.com/Linuxbrew/brew/issues/881 and it's work.
