Looking in the log I see the following configure line:

   ./configure --build=armv7hl-redhat-linux-gnu 
--host=armv7hl-redhat-linux-gnu --program-prefix= 
--disable-dependency-tracking --prefix=/usr --exec-prefix=/usr 
--bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc 
--datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib 
--libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib 
--mandir=/usr/share/man --infodir=/usr/share/info 
--host=armv7hl-redhat-linux-gnueabi 
LDFLAGS=-Wl,--as-needed,--library-path=/usr/lib


Notice that '--host' is there twice, and the two do not match:

    --build=armv7hl-redhat-linux-gnu
    --host=armv7hl-redhat-linux-gnu

    --host=armv7hl-redhat-linux-gnueabi


I think that second '--host=...' is what make configure try to cross 
compile the package, since it differs from the '--build'.  I'd check for 
where the second '--host'  was coming from, and why it is different from 
the first (and the '--build=...').
