    vmlinux.lds.h: catch .bss..L* sections into BSS")
    
    [ Upstream commit 1a7b7326d587c9a5e8ff067e70d6aaf0333f4bb3 ]
    
    Commit 9a427556fb8e ("vmlinux.lds.h: catch compound literals into
    data and BSS") added catches for .data..L* and .rodata..L* but missed
    .bss..L*
    
    Since commit 5431fdd2c181 ("ptrace: Convert ptrace_attach() to use
    lock guards") the following appears at build:
    
      LD      .tmp_vmlinux.kallsyms1
    powerpc64-linux-ld: warning: orphan section `.bss..Lubsan_data33' from `kernel/ptrace.o' being placed in section `.bss..Lubsan_data33'
      NM      .tmp_vmlinux.kallsyms1.syms
      KSYMS   .tmp_vmlinux.kallsyms1.S
      AS      .tmp_vmlinux.kallsyms1.S
      LD      .tmp_vmlinux.kallsyms2
    powerpc64-linux-ld: warning: orphan section `.bss..Lubsan_data33' from `kernel/ptrace.o' being placed in section `.bss..Lubsan_data33'
      NM      .tmp_vmlinux.kallsyms2.syms
      KSYMS   .tmp_vmlinux.kallsyms2.S
      AS      .tmp_vmlinux.kallsyms2.S
      LD      vmlinux
    powerpc64-linux-ld: warning: orphan section `.bss..Lubsan_data33' from `kernel/ptrace.o' being placed in section `.bss..Lubsan_data33'
    
    Lets add .bss..L* to BSS_MAIN macro to catch those sections into BSS.
