lang/clisp: Build with system compiler

[gerald]

Nice, thank you!

I made one specific comment re the LDFLAGS magic that predates your changes (this one and the ones in the last half year) and which I believe can be removed as well.

For the sake of completeness: Seeing how this now builds with clang, even should GCC be required for some reason yet unknown, -fpermissive should not be required any longer.

lang/clisp/Makefile

38–39

I believe these two can go as well. They were added with revision 511d74702f779

lang/clisp: fix build with GCC-based architectures

Add -lthr to LDFLAGS on GCC architectures.

While here, also add USES=localbase:ldflags.

PR:             237524

and I do not think we have GCC architectures left.

Plus with you removing USES=compiler, $CHOSEN_COMPILER_TYPE won't be defined any longer, so these two lines become noops anyway?
