This partly reverts commit 41e76d11dff6dd9bc08bf829751f9634f32cdd38. I
removed the "superfluous" errno-handling, which in fact is needed. Turns
out pathconf() might leave errno unchanged.

We required GL headers for shl_gl.h. Even though the linker strips all the
GL dependencies if it's disabled during compilation, we still require it
as build-time dependency. Avoid that by not including shl_gl in any non-GL

If the format string contains a trailing newline, we now skip writing our
own. We also skip the fn+file information as it would be written on the

Trailing newlines occur only when forwarding messages from other

Instead of generating C source files, we now use our binary-linker make
target which can link in any arbitrary binary file.
This way, we can delete genshader and instead link the files directly.
This speeds up compilation and makes the code more consistent.
We also strip the shaders from useless comments and whitespaces to reduce
memory consumption.

Shader sources may not be 0 terminated if we mmap() them. Hence, we need
to pass the length to the shader compiler. As glShaderSource() allows this
<0 as zero-terminated strings, we can simply add a parameter for the

The genshader and genunifont utilities are run during the build process
to generate source files. In order for that to work when cross-compiling
the files need to be built using the native compiler instead of the
cross-compiler.
Add the AX_PROG_CC_FOR_BUILD m4 macro which defines various *_FOR_BUILD
variables that are the native equivalents of CC, CFLAGS, LDFLAGS, etc.
Override CC, CFLAGS and LDFLAGS for genshader and genunifont and their
object files so that they will be built natively and can be executed
during the build.
