Query on avoiding generation of issignaling@GLIBC_2.18 symbols in libgfortran.so when building GCC-12.3 from sources

[Shubham Srivastava via Gcc-help <gcc-help@xxxxxxxxxxx>]

Hi,

When building gcc-12.3 with sources the libgfortran.so generated had issignaling*@GLIBC_2.18 symbols.
We need to avoid these GLIBC_2.18 symbols so that our apps/products can be supported on platforms like rhel7 that doesn't support these GLIBC symbols.
Is there any configuration option available that would help us avoid generation of these symbols in libgfortran.so
Any other suggestions or thoughts on how to avoid these symbols?

Kindly advise.

Best,
Shubham
