>Environment:
Linux PowerMacG5 4.19.0-1-powerpc64 #1 SMP Debian 4.19.13-1 (2018-12-30) ppc64 GNU/Linux
>Description:
In package makefiles that include '.include "../../mk/termcap.buildlink3.mk"' configure scripts say that the "C compiler cannot create executables".
In the config log at the compiler checking stage it states: "cc: Invalid transform rule: l:termcap:" causing the build to fail.

I have seen that this occurs on, at least, the readline and gettext-tools packages.

This also occurs on Debian Jessie on real hardware and in qemu
>How-To-Repeat:
(On ppc64(big endian) Linux)

cd /usr/pkgsrc/devel/readline
bmake

[build should fail with compiler cannot create executables]
>Fix:
In affected packages add an if statement specifying that:

if the operating system is linux and architecture is ppc64, .include "../../mk/curses.buildlink3.mk" else,  .include "../../mk/termcap.buildlink3.mk"

where applicable.
