Add patch to fix "bad regex" awk errors.

Fixes errors like the following:

    awk -f scripts/gen-sorted.awk \
           -v subdirs='csu assert ctype locale intl catgets math setjmp signal stdlib stdio-common libio malloc string wcsmbs time dirent grp pwd posix io termios resource misc socket sysvipc gmon gnulib iconv iconvdata wctype manual shadow gshadow po argp crypt nss localedata timezone rt conform debug libidn dlfcn elf' \
           -v srcpfx='' \
           nptl/sysdeps/pthread/Subdirs sysdeps/unix/inet/Subdirs sysdeps/unix/Subdirs assert/Depend intl/Depend catgets/Depend stdlib/Depend stdio-common/Depend libio/Depend malloc/Depend string/Depend wcsmbs/Depend time/Depend posix/Depend iconvdata/Depend nss/Depend localedata/Depend rt/Depend debug/Depend > /usr/src/eglibc_2.17~r22751+sip1-1/tmp/libcbuild/sysd-sorted-tmp
