newlib: Provide library name for ROM libc object files linked as PSRAM workarounds
Works around bug reported on forums where any source file ending in *lock.c or *creat.c was being linked to IRAM. https://esp32.com/viewtopic.php?f=13&t=8909&p=37362#p37362 Also moves all related functionality to newlib component.

# If the Newlib functions in ROM aren't used (eg because the external SPI RAM workaround is active), these functions will
|
||||
# be linked into the application directly instead. Normally, they would end up in flash, which is undesirable because esp-idf
|
||||
# and/or applications may assume that because these functions normally are in ROM, they are accessible even when flash is
|
||||
# inaccessible. To work around this, this ld fragment places these functions in RAM instead. If the ROM functions are used,
|
||||
# these defines do nothing, so they can still be included in that situation.
|
||||

|
||||
#
|
||||
# Note: We currently never link libg-psram-workaround.a, so no rules
|
||||
# are generated for this library
