[Interest] MSVC 2015, configure 64 bit, missing 'arch.exe'

[Philippe]

I don't have the problem with the 32 bit configure. But with the 64 bit,
I always get the following error during configure. Any idea?

Running configuration tests...
jom: C:\Qt\5.5.1\64\qtbase\config.tests\arch\Makefile [arch.obj] Error 2
Could not find output file 'arch.exe' or 'arch' in C:/Qt/5.5.1/64/qtbase/config.
tests/arch : No such file or directory
