Building DJGPP fails on Ubuntu 20.04 #20

https://github.com/jwt27/build-gcc/commit/98e62e0f1b145b2537326d9de4e3640071433f0e causes build to fail on Ubuntu 20.04 when targeting DJGPP:

checking whether to use python... /usr/bin/python2
checking for python2.7... no
configure: error: no usable python found at /usr/bin/python2
make[1]: *** [Makefile:9096: configure-gdb] Error 1
make[1]: Leaving directory '/home/manx/opt/djgpp-src/build-gcc/build/gdb-8.2.1/build-i386-pc-msdosdjgpp'
make: *** [Makefile:849: all] Error 2

I have both python2 and python3 installed.

This happens independently of whether /usr/bin/python is python2 or python3 (i.e. python-is-python2 or python-is-python3 packages installed).

Hi, thanks for the report. Seems gdb requires the Python C headers to be installed (package python2-dev). I should document this in the readme too.

Installing python2-dev solved the issue.

Thanks.
