Linking fails on hello_world example with disabled assertions (GIT8266O-836)

It looks like there are two sections: .flash.text and .flash.rodata which "start" should be in different 64 KB flash region.
Disabling asserts is reducing text section to very small one ( < 64 KB) and it causes above linking error.
For some reason, it is not a problem for linker if text and rodata share the same sector when text length is > 64 KB.

Anyway linking problem can be resolved by adding ALIGN(64K) to text section, as follows:

diff --git a/components/esp8266/ld/esp8266.project.ld.in b/components/esp8266/ld/esp8266.project.ld.in
index 54d7bb48..ce1decc2 100644
--- a/components/esp8266/ld/esp8266.project.ld.in
+++ b/components/esp8266/ld/esp8266.project.ld.in
@@ -175,6 +175,7 @@ SECTIONS
     *(.fini.literal)
     *(.fini)
     *(.gnu.version)
+    . = ALIGN (64K);
     _text_end = ABSOLUTE(.);
     _etext = .;

It fixes linking but it make binary file a little bit bigger. I'm not very familiar with ldgen, so if there is away to add this align conditionally, then it would be better solution.
