Review Request: 8005855: build-infra: Remove -R flag when cross compiling

Hi Erik:

common/autoconf/libraries.m4:

143 X_LIBS=`$ECHO $X_LIBS | $SED 's/-R.*//g'`

If I am reading this correctly, sed will delete everything from -R to 
end of line.  Is that correct?

Thumbs up if so - but this could have unexpected consequences if not.
