bits/sigset.h: Fix _EXTERN_INLINE redefinition
Commit 251a3c19cb "sleep: employ __USE_EXTERN_INLINES (with necessary fixes)" introduces following problems: 1. __USE_EXTERN_INLINES forcibly enabled build fails ... LD libuClibc-1.0.15.so libc/libc_so.a(cmsg_nxthdr.os): In function `__GI___cmsg_nxthdr': cmsg_nxthdr.c:(.text.__GI___cmsg_nxthdr+0x0): multiple definition of `__GI___cmsg_nxthdr' libc/libc_so.a(close.os):close.c:(.text.__GI___cmsg_nxthdr+0x0): first defined here libc/libc_so.a(creat.os): In function `__GI___cmsg_nxthdr': creat.c:(.text.__GI___cmsg_nxthdr+0x0): multiple definition of `__GI___cmsg_nxthdr' libc/libc_so.a(close.os):close.c:(.text.__GI___cmsg_nxthdr+0x0): first defined here ... 2. libuargp wrongly contains __cmsg_nxthdr/__sigismember/__sigdelset/__sigaddset global symbols on platforms which includes signal.h from sys/procfs.h As result, static linking will fail: TEST_LINK argp/ bug-argp1 /home/wbx/ppc-static/target_qemu-ppc-macppc_uclibc-ng_hard/usr/lib/libc.a(sigsetops.os): In function `__GI___sigismember': sigsetops.c:(.text+0x0): multiple definition of `__sigismember' /home/wbx/ppc-static/target_qemu-ppc-macppc_uclibc-ng_hard/usr/lib/libuargp.a(argp-xinl.os):argp-xinl.c:(.text+0x0): first defined here /home/wbx/ppc-static/target_qemu-ppc-macppc_uclibc-ng_hard/usr/lib/libc.a(sigsetops.os): In function `__GI___sigaddset': sigsetops.c:(.text+0x28): multiple definition of `__sigaddset' /home/wbx/ppc-static/target_qemu-ppc-macppc_uclibc-ng_hard/usr/lib/libuargp.a(argp-xinl.os):argp-xinl.c:(.text+0x28): first defined here /home/wbx/ppc-static/target_qemu-ppc-macppc_uclibc-ng_hard/usr/lib/libc.a(sigsetops.os): In function `__GI___sigdelset': sigsetops.c:(.text+0x4c): multiple definition of `__sigdelset' /home/wbx/ppc-static/target_qemu-ppc-macppc_uclibc-ng_hard/usr/lib/libuargp.a(argp-xinl.os):argp-xinl.c:(.text+0x4c): first defined here We have to partially revert 251a3c19cb to fix problems above. It is safe to do this after commit 162cfaea20 *: inline constant __sig{add,del}set and __sigismember since we are able to use new inlines from within libc and leave the rest of world(__USE_EXTERN_INLINES) equal to glibc now.
