  1. _G_va_list __ap, _IO_getc and _IO_putc fix 

    _G_config.h header file is not included in standard headers of Ubuntu-20.04, which defines _G_va_list.
_IO_getc and _IO_putc are not a part of the libc-2.31, leading to missing symbols error.
To fix it, extern(s) have been defined in case an executable linked with a libc supporting it is used, or if user provides an implementation for the same.

  1. Add glibc path existence checks 

    Check if the custom glibc install directory passed with --with-glibc exists or not.
Also, move the checks to the top of def configure(), to avoid any compiler checks in case wrong glibc location is passed.
