Installation of Ptlib

Fix a build issue with gcc-7.1.0 and later: 

sed -i "s/sbin\.Right(1) == '\\\\0')/strlen(sbin\.Right(1)) == 0)/" \
    src/ptclib/podbc.cxx &&
    
sed -i '/\/ioctl.h/a#include <sys/uio.h>' src/ptlib/unix/channel.cxx

Fix an issue with make-4.3 and later (breaks the build with previous versions of make): 

sed 's/\\#/#/' -i make/common.mak

Install Ptlib by running the following commands: 

patch -Np1 -i ../ptlib-2.10.11-openssl-1.1.0-1.patch &&
patch -Np1 -i ../ptlib-2.10.11-bison_fixes-2.patch &&

./configure --prefix=/usr  \
            --disable-odbc &&
make

This package does not come with a test suite.

Now, as the root user: 

make install &&
chmod -v 755 /usr/lib/libpt.so.2.10.11

Command Explanations

--disable-odbc: This parameter prevents the use of unixODBC-2.3.7, whose libraries conflict with ptlib. It is not needed if unixODBC-2.3.7 is not installed.
