Subject: [PATCH] build: configure-lib: List lib/windows/lseek.c once.

libmes_SOURCES takes lib/windows/lseek.c for mes_kernel=windows, as it
takes lib/linux/lseek.c and lib/stub/lseek.c for linux and gnu, and the
Windows block of libc_SOURCES named it a second time.  libc, libc+tcc and
libc+gnu, which all start from libmes_SOURCES, therefore defined lseek
and _lseek twice.  MesCC emits both, and hex2 resolves a label defined
twice to the later one, so the libraries MesCC builds were unaffected; a
compiler that rejects a redefinition, as TinyCC does, cannot build a
library concatenated from the list.

* build-aux/configure-lib.sh (libc_SOURCES): Do not list
lib/windows/lseek.c for mes_kernel=windows a second time.
