Our default uClibc configuration does not have DO_XSI_MATH=y, so it lacks certain math functions. jq generates some wrappers for the libm functions, even for functions that are not actually used by jq. By simply removing those wrappers, we get jq to build on uClibc that have DO_XSI_MATH disabled.

Subject: [PATCH] libm.h: comment j0, j1, y0 and y1

Those functions are currently not used by jq, but having them in
|
|
libm.h prevents building with the uClibc C library when it doesn't
|
|
have DO_XSI_MATH option enabled.
