Decreasing BSS size for STM32F4

[Мороз Олег]

looks like the BSS segment is depend from RAM_SIZE. I'm changing file 
called linkcmds:

MEMORY {
     RAM_INT : ORIGIN = 0x20000000, LENGTH = 128k

after building has

arm-rtems4.11-size shell.exe
    text       data        bss        dec        hex    filename
  364756      32256      98824     495836      790dc    shell.exe

.BSS is 98824


MEMORY {
     RAM_INT : ORIGIN = 0x20000000, LENGTH = 192k

arm-rtems4.11-size shell.exe
    text       data        bss        dec        hex    filename
  364756      32256     164360     561372      890dc    shell.exe

.BSS raised up to 164360


MEMORY {
     RAM_INT : ORIGIN = 0x20000000, LENGTH = 256K

arm-rtems4.11-size shell.exe
    text       data        bss        dec        hex    filename
  364756      32256     229896     626908      990dc   shell.exe


How can i fix the BSS size?
