Flex-2.6.4

Reference: 8.14. Flex-2.6.4. Fix the build system:

This package builds and installs the common way:

./configure --prefix=/qlnx \
            --includedir=/qlnx/inc \
            --mandir=/qlnx/man \
            --docdir=/tmp \
            --infodir=/tmp \
            --disable-static

Fix the newly created  libtool :

sed -i 's|/dev/null|/qlnx/dev/null|g' libtool

make
make install

Verify the loader (considered optional from now on):

readelf -l `which flex`

Create a symlink to run  flex  in lex mode:

ln -sv flex /qlnx/bin/lex
