Trial and error showed that it is enough to split the evaluation
into two expressions like
   x = 2*x + 1/(sqrtl(x*x+1)+x);
   x = logl(x);
to make the compiler happy. A similar change is necessary on another
line in the same file too.

Given the tweaks in

 arch/x86_64/syscall_arch.h     // let all __syscallN() call __syscall()
 src/env/__init_tls.c           // move #if conditional outside ()
 src/math/asinhl.c              // split log*() expressions

the compilation went through.
