Fix 'missing libc-version.h' build error (uClibc/x86[_64])

(fix commit 3d34255)

uClibc defines __GLIBC__ but does not contain libc-version.h file.

* include/private/gcconfig.h [(I386 || X86_64) && LINUX && __GLIBC__]
(GLIBC_2_19_TSX_BUG): Do not define (and do not include
gnu/libc-version.h) if __UCLIBC__.
