Subject: configure: add --cc= option to script
X-Git-Tag: fio-2.0.14~96
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=cb1125b0b197278894896af14fe8ecdf7b92756d;hp=aa83321fca5bb46d593d19d3863f511f80c01639

configure: add --cc= option to script

Get rid of uname -o usage for Windows, and specifically require
CC=bla ./configure or ./configure --cc=bla to set something else
than gcc.
